AD8349 Datasheet Quadrature Modulator

Manufacturer: Analog Devices

Overview: Data Sheet.

General 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 munication systems.

The differential LO input signal is buffered, and then split into an in-phase (I) signal and a quadrature-phase (Q) signal using a polyphase phase splitter.

Key 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.
