Also used as balanced mixers in lower frequency bands. The frequency stability looks quite good in my test setup even without any AFC connection. However I think in a practical application, AFC is required for optimum performance.

It was operated using 2xAA cells. You do not have the required permissions to view the files attached to this post. Is that a complete receiver? But for a practical tuner, you need them all. It's basically a part of superheterodyne implementation and I was only describing a way of front-end tuning. It's not complete.

Cheers, Andrea. Not sure if there is a Panasonic part in their 'AN' series. I would guess these are some kind of collaborative design or OEM concept. Whatever, these chips performs well in my testing and are highly recommended for low cost FM front end with excellent signal handling characteristics. THe built in RF amp offers good gain and sensitivity however, it is pretty much by-passable as you look onto the block diagram. For eg, a separate cascode or FET rf section can be tried out. The sony radio uses a one chip radio function without a separate FM front-end.

The mosfet as a mixer looks amazing in performance, and it will simply blow BJT related notorious mixing problems away without any critical wiring or performance tuning. And was also appeared very adaptive to LO drive levels wherever it is. There were no additional RF front required for local reception, the simply floating gate 1 of mixer with a wire attached to it seemed very sensitive to RF signals.

No BPF even used. I tested both BF and with equally good performance. Wonderful devices! During experiment, the climate was humid, my hands were wet and no carpets laying on the floor, I walked in with bare-foot In coming winter period Dec,Jan,Feb , I think better stay away from them!
