Cascode IF Amplifier Updates

"For The G6LBQ Irwell HF Transceiver"

Welcome to my blog post on the Cascode IF amplifier where, I address a problem that I discovered with the AM demodulator circuit and I also update the PCB to include the S-Meter electronics.

A note to self for future reference: 

"pay closer attention to manufacturers' product data sheets"

Cascode IF Amplifier With AGC For The G6LBQ Irwell HF Transceiver

 

HF Transceiver IF Amplifier Module

"Cascode IF Amplifier & AGC for the G6LBQ Irwell HF Transceiver Project"

In this blog post, I present details of  my Cascode IF amplifier with AGC function. The IF amplifier constitutes as a practical module for my HF multi-mode radio transceiver, which I call the "Irwell HF Transceiver".

My version of the Cascode IF amplifier is based on Wes Hayward's (W7ZOI) & Jeff Damm's (WA7MLH) as presented in QST magazine December 2007.
