100 KHz MF amplifier with dual gate MOSS-Fett
Original design by OZ8GG.
After using this in a homemade 2 meter SSB contest transceiver in many years, with a fine result, I now give it a try on 50 MHz with some "mods".
Done in EAGLE4.16:
MODS: Gate and Source is
lifted from ground to improve AGC, + 1.7 V with light-diode after an idé
in
EXPERIMENTAL METHODS IN RF-DESIGN, 2003.
The Coil is NEOSID: 600 uH
Gain: 100 db
Working perfect, no instability measured.
