[NLRS] MRF658 replacement for MRF648 in a 222 MHz amplifier?

[Jim Froemke]

I have an MRF658 that I'd like to use as a replacement for a blown MRF648 in
a 222 MHz amplifier however:
- The MRF648 "brief" data sheet says "applications up to 512 MHz".
- The MRF648 data sheet only lists specs. from 400 to 520 MHz.
So, has anyone used the MRF658 at any frequency below 400 MHz and in
particular at 222 MHz?

Comments would be appreciated.
