SPE EXPERT 1.3K-FA Solid State Linear Amplifier


When a design engineer is allowed to develop a product without regard to cost we usually end up with a product that offers great performance but at too high price.

Our goal was to design the best 1KW module in the world and then reduce the cost later. In a design where performance was top priority the cost of this product is still reasonably priced. This module is ideal for building W transmitters. With a P1dB point over W there is plenty of margin to overcome low pass filter and directional coupler losses. Most system integrators need to combine multiple modules for higher power. Thanks to 90 degree hybrids these modules can be combined using standard Wilkinson combiners.

Using any other filter may result in lower power output and voids all warranties. System integrators who plan to provide their own low pass filter must implement a diplexer with resistive harmonic absorber. This product is provided for experienced FM transmitter fabricators only.

If you are not experienced please buy a complete module or a rack-mounted completed amplifier. Please foresee a good RF choke also on the supply wiring. Generally best compromise between efficiency and harmonic emission, is obtained when the amplifier work at about dB of gain compression. They can be burned by applying too much drive power, too high supply voltage, not using proper heatsink, using filter with unsufficient specifications, connecting mismatched loads or no load at all and also by soldering coax with too long leads.

For this reason there is no warranty for any pallet. Only logged in customers who have purchased this product may leave a review. Home Shop Special sale items High quality W pallet amplifier.

To : amps contesting. Couple of points: I hope I didn't make any of my usual math mistakes. The SS amps I'm familiar with do use a modular approach. It's a flat pack rated at W out or double the MRFs and multiple units are relatively easy to cool.
