Designed for FM radio transmitters, with microstrip technology and a pair of 350W SD2942 RF mosfets.
There is a competition in the world of pallet amplifiers to offer the smallest possible amplifier. We decided not to compete for this prize at this power level. This is the only dual push-pull mosfet pallet amp with a 5 inch width. This layout is thermally superior to all of those 4 inch wide x 10 inch long PA's on the market. The SD2942's are rated at 350W each and 750W can be obtained by overdriving the mosfets a little but its not as bad as driving 300W mosfets to the same level. Taking a 300W mosfet to 375W places too much stress on the device.
Each pallet amplifier we sell is designed and tested on HP 8753 vector network analyzers for maximum performance.
Our amplifier products are manufactured using an automatic surface mount assembly process for high reliability.
This pallet is optimized for 48 volt operation. Using a lower voltage will result in lower efficiency and output power.
We sell a high quality 1000 watt low pass filter for FM broadcast applications.
