Description
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
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 μF capacitors.
Enable Pin. A high level enables the device; a low level puts the device in sleep mode.
Ground Pin for the Output Stage of Output Amplifier.
50 Ω 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 μF capacitors.
Q Channel Baseband Differential Input Pins. Inputs should be dc-biased to approxi-
mately 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.
