Condition
3GPP W-CDMA
HQPSK, 1DPCCH+1DPDCH
Input IQ signal driven differentially and in
quadrature.
At 40MHz offset
VCC=2.7V, T=+25°C, LO=975MHz to
990MHz at -10dBm, IQ=540mVP-P** at
100kHz, unless otherwise noted
GC=2.0V, IQ=0.8VP-P at HQPSK
GC = 2.0 V
Difference between output power at GC=2.0V
and GC=0.2V
Calculated between GC=1.0V and 0.5V
GC=2.0V, No I/Q adjustment
GC=1.5V, No I/Q adjustment
GC=1.0V, No I/Q adjustment
GC=0.5V, No I/Q adjustment
GC=2.0V, No I/Q adjustment
GC=1.5V, No I/Q adjustment
GC=1.0V, No I/Q adjustment
GC=0.5V, No I/Q adjustment
GC = 2.0 V
GC=2.0V, I/Q=540mVP-P at 100kHz
