1.3 KW Solid State Fully Automatic Linear Amplifier

RF SOLUTIONS is the authorised dealer for Australia/New Zealand

  • The smallest in its class:
    • Built-in power supply and optional built-in automatic antenna tuner
    • Dimensions: L 28cm, H 12cm, D 38cm (including connectors)
    • Weight without ATU: 10.5kg
  • The most technologically advanced solid state linear amplifier in the world:
    • Two powerful CPUs in use
    • More than 30,000 lines of software for performance unmatched in any other amplifier
  • Fully automatic:
    • Easy connection with transceivers from ICOM, Yaesu, Kenwood, Ten-Tec, FlexRadio, and Elecraft for immediate management of bands, tuner and antennas
    • Same performance with all makes and some homemade rigs
    • The operator only has to operate the transceiver, and the amplifier will follow automatically
  • Wide frequency coverage:
    • All amateur bands from 160m to 6m including WARC bands
    • 60m band, where permitted
  • Fully solid state:
    • Solid 1.3KW out; 50 MHz band included (+/- 0.5dB)
    • Switchable in MAX (full power), MID (900W) or LOW (500W), power selected according to the operator’s requirement or automatic for amplifier protection
    • No warm-up time required, amplifier ready immediately!
    • Using one LD / MOSFET  rated at 1.5KW out

    • PFC (Power Factor Correction)
  • The linear can be switched ON/OFF by switching the exciter ON/OFF
  • Can be used fully remotely
  • A large LCD display allows a great deal of information:
    • Watts pep out, Vpa, Ipa, Watts, temperatures, SWR (after and before the ATU), input setting, CAT setting, band and other indications including the alarms log
  • Easy to operate:
    • Powerful and sophisticated software gives you a user-friendly unit
  • USB / RS232 ports:
    • For remote control
    • For new software releases download
  • Easy transportation: 
    • A sturdy carry-bag is supplied for QSY, Field Day, DXpeditions etc.
  • Certifications:

    • RCM (C-Tick), CE, FCC


Optional ATU can be added later

Warranty Terms

RF SOLUTIONS supports the manufacturer’s warranty as stated below:

For a period of two (2) years from the invoice date, SPE / Distributor warrants in the EU, at authorized laboratories, the free repair of manufacturing defects and the free replacement of defective components.

Each power LDMOS/MOSFET is guaranteed for the first 3 months and for a single replacement.

The warranty is not applicable in the cases specified below.

The Purchaser only has to pay all the shipping expenses in both directions.

Customers should address requests for warranty service work to the Distributor/Dealer where they made their purchase.

As part of their reseller agreement with SPE, they are fully responsible for service support.

If the Distributor/Dealer has closed down and if he is not replaced, SPE will be directly responsible for warranty service at their factory in Rome. The shipping expenses to and from SPE will then be paid by the customer. Any repair requests to other dealers will be subject to specific direct negotiations between the customer and the dealer.

In order to not invalidate the warranty service, the original Purchaser must complete the warranty registration card, and send it to SPE within 30 days from the date of purchase.

Unless otherwise agreed, the products will be delivered ex-works from the factory of the seller.

The delivery, even in the event of a return for repair, is understood done with the delivery of the goods to the carrier specified by the purchaser or, failing that, to the carrier chosen by SPE or the Distributor/Dealer.

The products will travel at the risk of the purchaser even if, at the request of the same one or for other causes, SPE should carry out transport or choose the carrier.

If the original Purchaser finds some defects after having received the equipment, he must immediately notify the Distributor/Dealer of the defects found by sending the completed REPAIR FORM. Replacement of the amplifier may be offered by SPE in exceptional circumstances only and at SPE’s complete discretion. However, no replacement will be offered after 21 days of original purchase. 

In case of a purchase of a used amplifier, in order to retain the warranty’s validity, it is necessary to notify SPE of the following data:

  • Document for the second purchase (used)
  • Invoice for the original purchase
  • Serial number (s/n) of equipment

Replacement of equipment in these circumstances is not an option.

In any case the warranty period shall be as specified from the date of original purchase, and not from any subsequent purchase. However, the limitation for the power LDMOS/MOSFET remains as outlined above, i.e. the warranty period for the power LDMOS/MOSFET device/s is limited to three months only. If the power LDMOS/MOSFET has been damaged due to incorrect usage, it is not covered under warranty.

Whenever the date of the first sale is not well specified, the date of shipping from SPE to the Distributor/Dealer will be considered the start of the warranty period.

The warranty does not apply either if the certificate of the first purchase (invoice) is missing, the s/n is undecipherable / falsified or to any defect that SPE determines is due to the following:

  1. Improper maintenance or repair by persons not authorised by SPE to carry out such work, including the installation of parts or accessories that do not conform to the quality and specifications of the original parts.
  2. Acts of nature such as lightning, storm & tempest, moisture or water intrusion, fire.
  3. Misuse, abuse, neglect or improper installation, user’s manual non-observance.
  4. Carelessness, accidental or intentional damage.
  5. In the manual of the transceiver used it is clearly written that  it cannot be  used with a solid state amplifier.

In addition, and more specifically possible damage caused by incorrect usage such as:

  • Exceeding power ratings of antennas, insufficient impedance transformers and insufficient baluns.
  • RFI in the shack.
  • Low gate isolation due to the initial spike of the transceiver.
  • Repeated input overdriving alarms.
  • Repeated high SWR alarms.

SPE warrants only manufacturing defects and defects in the materials used, NOT inherent and consequent damages.

It is mandatory, when sending SPE equipment to be repaired, to enclose:

  • Invoice of the original purchase.
  • Document of the second purchase (if any).

Particular agreements between retailer and Purchaser or particular obligations imposed in other countries are matters for the local retailer and not for SPE.

In the event of dispute Rome’s court of competent jurisdiction will apply.

The Purchaser declares his acceptance of the above Warranty Terms.


With the release of the new SPE EXPERT 1.5K-FA, this does not mean that the SPE EXPERT 1.3K-FA has been superseded.  The SPE EXPERT 1.3K-FA is still very much a current model.

In fact, these are two wonderful products with some important differences designed into each amplifier in order to best cover the varying needs of our customers.

Dimensions and weight are identical between the two amplifier models.

This means that we keep the unmatched portability of the 1.3K-FA for the DXpeditions, which has made this amplifier irreplaceable and unmatched.

The differences between the 1.3K-FA and the 1.5K-FA are as follows:

(Please note that all other features are identical in the two models.)


  • Solid 1.3KW PEP on every band and mode.
  • Available with or without ATU.


  • Solid 1.5KW output on every band and mode.
  • Pre-distortion output connector for incredible linearity with SDR.
  • Only available in one version with built in ATU, which also complies with the FCC requirements.

Launch of the third series of SPE EXPERT 1.3K-FA and 1.5K-FA amplifiers

As is now well known, most of the transceivers on the market today have an issue with a strong spike at the beginning of each transmission, causing damage to both solid-state and some tube amplifiers.

This spike is present, even if you manually reduce the output power on the transceiver.

Amplifiers using LDMOS are particularly susceptible to the spikes, compared to the previous RF power mosfet generation.

In accordance with SPE’s commitment to continuous improvement of our products, we have developed a proprietary circuit which cancels any type of spikes.

This is not a simple clipper but a complex hardware circuit, not a single component, faster than the very fast LDMOS.

Unfortunately, this hardware modification cannot be applied to previous series of the SPE EXPERT amplifiers.

The slowdown of the manufacturing industry and parts availability due to the pandemic has allowed SPE to focus on and complete these upgrades.

All SPE EXPERT amplifiers delivered from September 2021 will be “Third series”.
