PRODUCT DESCRIPTION
The F-MOD family of monolithic, RF quadrature modulators is
designed for use from 300 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 3 dB baseband bandwidth in excess of
500 MHz 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.
