NOTE
The action of the anti-jam circuit to centre the bandwidth of the receiver around the wanted modulated signal at 433·92 MHz, 20kb/s, 50% duty
cycle,
2
90dBm Also notice the ability of the receiver to achieve the same selectivity performance over the frequency range 433 to 434.5 MHz
with and wthout a SAW filter.
NOTE
Unmodulated interfering signal is 100kHz low side from wanted signal. Both signals are within the passband of the receiver (ceramic filter)
i.e.
Wanted signal = 433·92 MHz at 2kb/s,
2
90 to 0dBm (50% duty cycle)
Interfering signal = 433·82MHz continuous carrier,
2
90 to 0dBm
