description

The TRF3520 radio frequency (RF) modulator/amplifier is a single-chip RF integrated circuit (IC) suitable for

900-MHz wireless global system for mobile communications (GSM) applications. It combines a direct

conversion RF in-phase/quadrature-phase (I/Q) modulator, a single-sideband suppressed carried (SSB) mixer,

an RF filter, a power amplifier (PA) driver, a buffered voltage-controlled oscillator (VCO), and a serial interface

into one small package. Very few external components are required. During idle operation, the individual

functional elements may be selectively placed in standby mode for minimum power consumption.
