QRP PA

QRP PA

QRP PA

See earlier work in December 2017. After that I made a PCB and have now mounted and tested the first board. It is inspired from K5BCQ and from  DK1HE QRP-PA.

Not as god as I hope, but working.

+10dBm iN,

OUT  @ 1.8 MHz  41,3 dBm

          @  7,1 MHz 43,3 dBm

          @ 28,4 MHz 41,0 dBm

          @ 52 MHz 39,2 dBm

RL < -15 1,8 – 52 MHz

Current 2,5 +/- 02A

I hope it will be in one more QRP transceiver  I have ides for, we will se!

There  is also an USB to serial board on the back panel.

I have some PCB over if you are interested e-mail.
