FM radio amplifier with broadband matching and a BLF177 MOSFET

This new design incorporates a 4:1 broadband coaxial transformer matching scheme. The result is high efficiency and improved frequency response.
We also added diode temperature compensated bias for enhanced performance over temperature.
New bias disable pads facilitate integration into amplifier systems that employ automatic VSWR protection. Taking this pad to ground will shut down the amplifier.

Mechanical information is available in DXF Fromat or PDF format.
Each pallet amplifier we sell is tested on an HP 8753D vector network analyzer.
This amplifier is capable of 150 watts.
Our amplifier products use ATC/AVX microwave chip caps for high reliability.
This pallet is optimized for 48 volt operation. Using a lower voltage will result in poor efficiency and significantly lower output power; however, 28 volt operation is possible.
We sell a high quality 500-1000 watt low pass filter for FM broadcast applications.
