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. Pout [dBm] Four Carrier PSD in 30kHz BW -20 -30 -40 -50 -60 -...
