I Channel Baseband Differential Input Pins. These high impedance inputs should
be dc biased to approximately 0.7 V. Nominal characterized ac swing is 0.6 V p-p
on each pin (0.4 V to 1 V). This gives a differential drive of 1.2 V p-p. Inputs are
not self-biasing so external biasing circuitry must be used in ac-coupled applications.
Ground Pin for Input V-to-I Converters and Mixer Core.
Ground Pin for the LO Phase-Splitter and LO Buffers.
Differential LO Drive Pins. Internal dc bias (approximately 1.8 V @ V
S
= 5 V)
is supplied. Pins must be ac-coupled. Single-ended or differential drive is permissible.
Power Supply Pin for the Bias Cell and LO Buffers. This pin should be decoupled
using local 1000 pF and 0.01
μ
F capacitors.
Enable Pin. A high level enables the device; a low level puts the device in sleep mode. Circuit C
Ground Pin for the Output Stage of Output Amplifier.

DC-Coupled RF Output. Pin should be ac-coupled.
Power supply pin for baseband input voltage to current converters and mixer core.
This pin should be decoupled using local 1000 pF and 0.01
μ
F capacitors.
Q Channel Baseband Differential Input Pins. Inputs should be dc biased to
approximately 0.7 V. Nominal characterized ac swing is 0.6 V p-p on each pin
(0.4 V to 1 V). This gives a differential drive level of 1.2 V p-p. Inputs are not
self-biasing so external biasing circuitry must be used in ac-coupled applications.
