30 W FM Pallet Amplifier

It is designed to use in FM transmitters. Output power can be adjusted via 0-12Vdc control voltage. 

It is used inside 30W FM exciters and also inside compact transmitters and amplifiers. The RF power transistor BLF245 is drived by 2N4427.

A low pass filter with on board directional coupler connected to the pallet amplifier on an heatsink. There is DC outputs to measure forward and reflected powers and monitor to measure RF output. All necessarry DC voltages for your control system are ready on the unit less than 3Vdc.

NOTE: Pallets are sensitive devices if you do not have sufficient experience please consider a finished product instead. They can be burned by applying too much drive power, too high supply voltage, not using proper heatsink, using a 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. We do assure you that every pallet is tested and is 100% operational as it leaves our workshop.
