SA616
Low-voltage high performance mixer FM IF system
[1] This is a 30 kHz bandwidth 455 kHz ceramic filter. Al the characterization and testing are done with this
wideband filter. A more narrowband 15 kHz bandwidth 455 kHz ceramic filter that may be used as an
alternative selection is Murata CFUKG455KE4A-R0.
[2] R5 can be used to bias the oscillator transistor at a higher current for operation above 45 MHz.
Recommended value is 22 k, but should not be below 10 k.
