TEST CONDITIONS
Note 1:
Conversion Gain Shift
Measure conversion gain change when VCC±10% with input level = 50dBmW, VCC = 9V as the
reference.
Note 2:
Frequency Shift
Measure frequency change when VCC±10% with input level = 40dBmW, VCC = 9V 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+12MHz 100kHz, 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+1MHz
Input the two signals above, and increase the input levels.
When the IF output level is 11dBmW, measure the suppression level.
(Averaging 10 times using a spectrum analyzer.)
