General 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.
