SAW Filter
The 1st IF filter is a SAW filter. The function of the filter is to provide at-
tenuation for the intermodulating signals
Analog IF parts
Analog mode IF–parts are included in EROTUS. Functional blocks: IF1
amplifier, a 2x–multiplier for LO signal, a mixer and a limiter amplifier
with RSSI. Specifications for analog mode IF–parts are in table 5. IF2
filter is a double 450 kHz ceramic filter.
