NF meter direct-reading value (DSB measurement)
Measure maximum IF output level.
Conversion gain shift is defined as change in conversion gain when supply voltage exceeds ranges
Frequency shift is defined as change in oscillator frequency when supply voltage exceeds ranges
Measure phase noise at 10-kHz offset.
Measure worst-case local-leak level for RF pin (with IF output pin open).
Measure worst-case local-leak level for IF pin (with RF input pins shorted using 50-W resistor, and
RF input level = -40dBmW
Measure selected IF output pin’s level, and not selected IF output pin’s level.
Ifiso = |(selected IF output pin’s level ) - (not selected IF output pin’s level)|
Not selected IF output pin shorts using 50 W resistor.
Calculate IF output intercept point as follows:
1 = 5 V to 4.5 V or V
= 5 V to 4.5 V or V
IP3 = S/(N - 1) + P [dBmW]
S: suppression level
