AD8349 - Quadrature Modulator

Description

The AD8349 is a silicon, monolithic, RF quadrature modulator that is designed for use from 700 MHz to 2700 MHz.

Its excellent phase accuracy and amplitude balance enable high performance direct RF modulation for communication systems.

Features

  • Output frequency range: 700 MHz to 2700 MHz Modulation bandwidth: dc to 160 MHz (large signal BW) 1 dB output compression: 5.6 dBm @ 2140 MHz Output disable function: output below.
  • 50 dBm in < 50 ns Noise floor:.
  • 156 dBm/Hz Phase quadrature error: 0.3 degrees @ 2140 MHz Amplitude balance: 0.1 dB Single supply: 4.75 V to 5.5 V Pin compatible with AD8345/AD8346s 16-lead, exposed-paddle TSSOP package.
