    HI, I have installed 100 ohms in R55 input to limit gain and now am wondering what value resistor to use for R97, R98 (same value) assuming that R94 and R100 stay the same for attenuation into the PA stage. Or the Db loss needed.


            Thank you      Gil    K8EAG

Hi Gil,

I haven't stuffed R97 and R98. Default values of R94 and R100 are fine. Just be careful when running at full power at first and make sure your power output is not too high (6-7W is okay) and your LDMOS devices are not becoming too hot during TX.

73,
