TA1375FG
(see2) IF Output Power Level
Measure IF output level when It is maximum level.
(see3) Conversion Gain Shift
The conversion gain shift Is defined as a change In conversion gain when supply voltage varies from Vcc=5V to 4.5V or
From Vcc=5V to 5.25V.
(see4) Noise Figure (MO)
Noise figure meter used. Direct reading.
(see5) OSC Frequency Shift (The PLL is not operating)
The frequency shift Is defined as a change In oscillator frequency when supply voltage varies from Vcc=5V to 4.5V or
From Vcc=5V to 5.25V.
(see6) Switch ON Drift (The PLL is not operating)
Measure frequency change from 2 seconds after switching on to 3 minutes.
(see7) 1% Cross Modulation
z fd = fp : (fd Input level = -30dBmW)
z fud = fp ʶ12MHz, 100kHz AM30%

Input two signals, and Increase the fud Input level.
Measure the fud Input level when the suppression level reaches 56.5dB.
(see8) 3^rd Internal Modulation (MO)
z fd = fp : (fd Input level = -30dBmW)
z fud = fp ʶ1MHz : (fud Input level = -30dBmW)
Input two signals, measure the suppression level.
(see9) Phase Noise (1kHz offset)
Measure the phase noise at 1kHz offset. (PLL setting; frequency step = 62.5kHz / charge pump current = High mode)
RF Input level = -30dBmW
(see10) Phase Noise (10kHz offset)
Measure the phase noise at 10kHz offset. (PLL setting; frequency step = 62.5kHz / charge pump current = High mode)
RF Input level = -30dBmW
