PRODUCTION

Aerospace 2.5 GHz Direct Conversion Quadrature Modulator

Viewing:

Overview

  • Output Frequency range 800 MHz to 2.5 GHz
  • I/Q Base-band Frequency range dc – 70 MHz
  • Output Power –3 dBm P1 dB
  • Noise Floor –147 dBm/Hz
  • Quadrature Phase Accuracy 1 deg rms
  • Amplitude Balance 0.2 dB
  • Low Power with Power Down Function
  • Single 2.7 V – 5.5 V Supply

The AD8346S is a silicon I / Q quadrature modulator, designed to be used from 800MHz to 2.5GHz. The part is optimized for lower power applications, yet provides a very low noise floor and high output power for the given supply current.

The AD8346S requires only –10dBm LO drive level and provides a fully specified 50 ohm buffered output.

The part provides excellent amplitude and phase balance and sideband suppression specifications to enable higher order / capacity QAM modulated radios.

Additionally the AD8346S has been tested and provides –72dBc ACPR when used in a direct up-conversion CDMA IS95 modulator.

The AD8346S is supplied in 16-lead Bottom Brazed Flat Pack package, and fully specified over –55 to 125 deg C temperature range.
