GND

These pins and the ground paddle should be

connected to a high quality RF/DC ground.

LOP, LON

LO inputs. Need DC decoupling capacitors.

The ports could be driven single ended or differentially.

TE QN, QP

Q channel differential baseband input. These high

impedance ports should be biased around 1.5V DC.

Nominal recommended baseband input is around

1.6V pp differential.

LE RFOUT

RF output. 50 Ohms. Needs DC blocking capacitor.

O Vcc1

OBS IP, IN

Supply voltage for the mixer and

output stages 79mA @ +5.0V.

I channel differential baseband input.

These high impedance ports should be at the

same bias voltage (VbbDC) as Qn & Qp.

24

Vcc2

Supply voltage for the LO stage 88mA @ +5V.
