Iinb
VCC/2
–
Input for I signal. This input
impedance is 200 kΩ. In the case of
that I/Q input signals are single
ended, amplitude of the signal is
500 m VP-P max.
–
Input for I signal. This input
impedance is 200 kΩ. In the case of
that I/Q input signals are single
ended, VCC/2 biased DC signal
should be input. In the case of the
I/Q input signals are differential,
amplitude of the signal is 500 m VP-P
max.

This pin is not connected to internal
circuit. This pin should be opened
or grounded.

VCC 2.7 to 4.0
–
Local signal input for modulator.
This pin must be coupled with DC
cut capacitor 330 pF and should be
terminated with 51 Ω resistor.
Supply voltage pin for modulator,
up-converter and AGC circuits.
