ADDITIONAL PRODUCT PERFORMANCE CHARACTERISTICS (NOT TESTED IN PRODUCTION):

General notes: A-weighting filter, RF testing level = -70 dBm, 33kHz Deviation @ 1 kHz modulation frequency, unless oth-
erwise specified.
Audio & RF tests at the detector output:
Audio level : 100 mV RMS min
S/N Ratio: 50 dB min. (60dB typical)
Frequency response: (100 Hz - 15 kHz) [+/-4.0 dB]
IF Bandwidth test at the detector output:
THD at fc+25 kHz: 2 % max.
THD at fc-25 kHz: 2 % max.
Image Response tests:
1st image rejection: 40 dB min. (50 dB typical)
2nd image rejection: 70 dB min.
½ first IF response test: 50 dB min.
2/3 first IF response test: 50 dB min.
½ 2nd IF test: 70 dB min.
2/3 2nd IF test: 70 dB min.
Response at Fo +/- digital clocks and their harmonics: 60 dB min.
Parasitic spurious: 50 dB min.
RF conductive tests:
First LO and its harmonics at the antenna port: -70 dBm max.
Second LO and its harmonics at the antenna port: -80 dBm max.
Overload test:
No receiver performance degradation should be observed at RF input levels up to -25 dBm. (THD, SINAD and S/N)
Intermodulation, THD, SINAD and S/N degradation is expected at RF input levels between
-20 to 6 dBm, however the receiver should receive the signal as expected.
Intermodulation tests:
Receiver's response to the 3rd and 5th order IM products outside of the bandwidth of the
second IF filters (e.g.: f (on channel) = 800MHz, F(IM1) = 801 MHz, F(IM2) = 802MHz) should be better than 50 dB.
Basic stability tests:
At the threshold of receiver's sensitivity, there should be no extraneous noises being generated within the receiver's circuit-
ry. There should be no parasitic oscillations present during tests with a spectrum analyzer along receiver's signal path (RF
band, 1st mixer, 1st IF, Second Mixer, Second IF, Detector, audio and noise circuitry).
RSSI tests:
RSSI total dynamic range: -100 to -60 dBm
