Are there any low cost (<$10) barrel type limiters for SMA with
anti-parallel ordinary diodes in there? Female with nut on one side,
male sans nut on the other.
I know, I know, this ain't the proper way to do it because of
intermodulation. But it's the usual scenario. Units out in the field, a
bit late in the game, receiver inputs croaking, swapping the whole board
would be a bear. What I found at the usual RF places are costly and
fancy PIN diode limiter setups, often controllable via a DC voltage.
That's overkill in this case. I just need something that cuts hard to
about +/-700mV and can be non-linear. A BAV99 works just fine but I'd
hate to use a Tee and roach it on there.
