John - That part is actually the low-pass filter used on the output of the power amplifier to prevent harmonics from leaving the unit.
It is a pretty good filter, with about 1 dB insertion loss up to 180 MHz, and 3 dB at 200 MHz. After that it falls off pretty fast. Here are my measurements on one unit I have - 200 MHz - 3 dB 206 MHz - 10 dB 216 MHz - 20 dB 230 MHz - 30 dB 234 MHz - 40 dB 259 MHz - 50 dB 275 MHz - 60 dB John - WB4YJT, Sacramento ============================================================= --- In [email protected], DCFluX <dcf...@...> wrote: > > Looks like a VHF Micor Transmitter Low Pass Filter to me. > > On Tue, May 11, 2010 at 10:19 AM, La Rue Communications <laruec...@... > > wrote: > > > > > > > Need some help here.
