Test Conditions
Note 1: Conversion Gain Shift
Measure conversion gain change when VCC±10% with input level = 50dBmW, VCC = 5 V as the reference.
Note 2: Frequency Shift
Measure frequency change when VCC±10% with input level = 40dBmW, VCC = 5 V as the reference.
Note 3: Switching On Drift
Measure frequency change up to 3 minutes with the frequency at 2 seconds after switching on as the
reference. (Input level : 30dBmW)
Note 4: 1% Cross Modulation
fD = fP fD : input level = 30dBmW
fUD = fD+12 MHz 100 kHz, 30%AM
Input the two signals above, and increase the fUD input level.
Measure the fUD input level when the suppression level reaches 56.5dB. (Averaging 10 times using a
spectrum analyzer)
Note 5: Inter Modulation
fD = fP
fUD = fD+1 MHz
Input the two signals above, and increase the input levels.
When the IF out level is 11dBmW, measure the suppression level. (Averaging 10 times using a spectrum
analyzer)
