Designed for FM
transmitters, like any other pallet amplifier it requires a heatsink,
output filter and usually also a fan.
- This 150W pallet requires 48V/6A power supply. It can provide up to
185W of output power with about 4-5W of drive. The SD2941-10 is the latest technology from ST Microelectronics, this new design incorporates a 4:1 broadband coaxial transformer
matching scheme. The result is high efficiency and improved frequency
response. 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). We offer high quality 300-1000 watt low pass filters for FM broadcast
applications. We can also supply suitable heatsink and fans. Please use teflon coaxial cable (RG142) for
input and output coaxial cable.
