Product Details

The ADAR2004 is a 4-channel receiver IC intended to work with the ADAR2001 transmitter in millimeter wave body scanning applications. Accepting differential input signals from 10 GHz to 40 GHz, the ADAR2004 provides a low frequency IF output up to 700 MHz. Each receive channel also has independent gain control.

The mixer LO path includes a 4x multiplier requiring an applied LO frequency between 2.5 GHz to 10 GHz. The 4x multiplier block includes a programmable filter which helps keep harmonics below -25 dBc to -30dBc at all frequencies..

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

The ADAR2004 requires only a single 2.5 V supply with power consumption of 985mW with all channels turned on.

The ADAR2004 comes in a 7x7mm package with 48 pins.
