HOT new product, first 1200W pallet 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. In terms of performance it is in a class of its own at a price that is much lower than a 3 x SD2942 or 4 x BLF278/MRF151G.
- 43-50 Volts @ 32 - 34ADC
This module is ideal for building 1000W transmitters. With a P1dB point over 1200W 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. 90 degree combining provides the best impedance match; therefore, driving low pass filters and combiners results in much lower reactions and losses.
Model PCS LPF 1200W is the only qualified low pass filter for this product. 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 will reduce the amount of heat produced by RF output LDMOS and extend the life expectancy of the amplifier.
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.
