4123Balanced Antenna Amplifiers
- Oct 1, 2007About a year ago we had a lengthy discussion about active antenna
amplifiers, and someone posted a URL for a balanced amplifier that had a
pair of JFETs followed by a pair of NPNs. I think it had four varactors for
tuning. I remember having made a comment about adding a transformer between
the JFETs and the NPNs to improve the gain and the even-order distortion.
Somehow, I mananged to misplace that schematic and would like to ask if the
person who earlier made that avialable would do so again.
