Title: Two-balanced RX mixer
Post by: satoryboy on 12. April 2021, 07:13:54
I am posting for discussion a modified circuit of a two-balanced RX mixer. The gain is 11 for both inputs of the differential amplifiers, the input impedances are 2.2 kOhm. Not much, but in the classic mcHF circuit there is generally 100 ohms.

I suggest you try these changes that I applied to the Eagle last year. '73 IZ6MAF Paolo
