Overview

Features and Benefits

  • Based on the ADAR2004 4-Channel Rx Mixer with 4x LO
  • Controllable through SPI
  • Multiple forms of digital interface (3.3 V and 1.8 V logic)
  • On-board logic level translators with 1.8 V low dropout regulator for supply
  • Software control from a Windows-based PC through USB

Product Details

The ADAR2004 is a 4-channel receiver IC that is optimized for millimeter wave body scanning applications. Accepting differential input signals from 10 GHz to 40 GHz, the ADAR2004 provides a low intermediate frequency (IF) output up to 800 MHz. Each receive channel also has independent gain control.

All device functions and configuration options can be accessed by a 3-wire or 4-wire Analog Devices, Inc., serial peripheral interface (SPI).

The mixer local oscillator (LO) path includes a 4x multiplier requiring an applied LO frequency between 2.4 GHz to 10.1 GHz. The 4x multiplier block includes a programmable filter that helps keep harmonics down before hitting the mixer.

Two programmable state machines are included to facilitate simple configuration, control, and fast switching of the frequency multiplier/filter, and receiver sections. These sequencers are programmed through the SPI and are then operated by pulsed inputs (reset and advance).

The ADAR2004 requires only a single 2.5V supply with power consumption of 910 mW with all channels turned on.

The ADAR2004 is available in a 7 x 7 mm, 48-terminal LGA package and is specified from -40°C to +85°C.
