1Iin
VCC/2
–
Input for I signal. This input
impedance is 200 k
Ω. In the case of
that I/Q input signals are single
ended, amplitude of the signal is
500 m VP-P max.
2Iinb
VCC/2
–
Input for I signal. This input
impedance is 200 k
Ω. 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.

4Qinb
VCC/2
–
Input for Q signal. This input
impedance is 200 k
Ω. In the case of
that I/Q input signals are single
ended, amplitude of the signal is
500 m VP-P max.
5Qin
VCC/2
–
Input for I signal. This input
impedance is 200 k
Ω. In the case of
that I/Q input signals are single
ended, VCC/2 biased DC signal
should be input. In case of the I/Q
input signals are differential,

Local signal input for modulator.
This pin must be coupled with DC
cut capacitor 330 pF and should be
terminated with 51
Ω resistor.
