Munin - Munin is a 100W HF power amplifier for Penelope and/or Hermes. This amplifier is dependent on the Alex LP filters
The 100W PA uses a pair of RD100HHF1 in the output. They are driven by a pair of RD15HVF1 and there is also a predriver with one RD06HVF1 to get higher gain to be used with low power exciters. I have built 1 Alpha unit and it works very fine. The PEP output with -30dB 3.rd order IM is >90W on all bands from 1,5 to 55 MHz. The gain is within +- 2dB for the same frequency band. -- please see the HPSDRwiki at link below for current details.
The project leader for Munin is Kjell, LA2NI.
