A signal amplifier module for HF


Marcus Jenkins blogged about his radio frequency amplifier project he made using DirtyBoard PCB’s

In building QRP HF radios, having an RF signal level amplifier building block is handy. You want 50 Ohm output impedance, some reasonable gain, supply voltage of the usual 10-14V and ease of building using standard parts from your parts bin. Some searching around the interwebs came up with a good idea for circuit from Aaron Parks, KC8FQD, who did a YouTube video on a WWV receiver.

  1. I have always thought of high frequency (RF and above) as the black magic part of electrical engineering. Congrats and thank you for the informative writeup.
