PRODUCT DESCRIPTION
The F-MOD family of monolithic, RF quadrature modulators is
designed for use from 250 MHz to 4000 MHz. Excellent phase
accuracy and amplitude balance enable high performance direct
RF modulation for communication systems.
The F-MOD family can be used as direct-to-RF modulators in
digital communication systems such as GSM, CDMA, and
WCDMA base stations, and QPSK or QAM broadband wireless
access transmitters. A 700 MHz 3 dB baseband bandwidth
makes it ideal in broadband Zero-IF or Low-IF-to-RF
applications and in broadband Digital Pre-Distortion
transmitters.
The F-MOD family is fabricated using Analog Devices’
advanced Silicon-Germanium bipolar process, and are available
in a 24-lead exposed-paddle LFCSP package. Performance is
specified over a –40°C to +85°C temperature range.

Description
Input Common Pins. Connect to ground plan via a low impedance path
Positive Supply Voltage pins. All pins should be connected to the same supply. To ensure
adequate external bypassing, connect 0.1 µF capacitors between each pin and ground.
Adjacent power supply pins of the same name can share one capacitor (see evaluation
board schematic).
Differential In-Phase and Quadrature Baseband Inputs. These high impedance inputs must
be dc-biased to approximately 500 mV dc, and must be driven from a low impedance
source. Nominal characterized ac signal swing is 700 mV p-p on each pin. This results in a
differential drive of 1.4 V p-p with a 500 mV dc bias. These inputs are not self-biased and
must be externally biased.
50 Ω Single-Ended Local Oscillator Input. Internally dc-biased. Pins must be ac-coupled. AC-
couple LOIN to ground and drive LO through LOIP.
Device Output. Single-ended, 50 Ω internally biased RF output. Pin must be ac-coupled to
the load.
