Condition
GC=2.0V. Extrapolated from IM3 with two
baseband tones at 90kHz and 110kHz applied
differentially, in quadrature, at both I and Q
inputs, each tone 400mVP-P.
GC = 2.0 V
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
FLO LB leakage
Second harmonic of carrier
Third harmonic of carrier
I/Q = 100 kHz
