Lo1 input for phase shifter.

This input impedance is 50 Ω

matched internally.

2

Lo1in

−

2.4 Bypass of Lo1 input.

This pin is grounded through

2

internal capacitor.

Open in case of single ended.

3

GND for

0

modulator

−

Connect to the ground with

minimum inductance.

Track length should be kept as

short as possible.

I

VCC/2

−

Input for I signal. This input

impedance is larger than 20 kΩ.

Relations between amplitude

and VCC/2 bias of input signal

are following.
