The ADAR2004 is a 4-channel receiver IC that is optimized formillimeter wave body scanning applications. Accepting differentialinput signals from 10 GHz to 40 GHz, the ADAR2004 provides alow intermediate frequency (IF) output up to 800 MHz. Eachreceive channel also has independent gain control.The mixer local oscillator (LO) path includes a 4× multiplierrequiring an applied LO frequency between 2.4 GHz and10.1 GHz. The 4x multiplier block includes a programmable filterthat helps keep harmonics down before reaching the mixer.
Two programmable state machines are included to facilitatesimple configuration, control, and fast switching of the frequencymultiplier, filter, and receiver sections. These sequencers areprogrammed through the serial peripheral interface (SPI) andare then operated by pulsed inputs (reset and advance).
The ADAR2004 requires only a single 2.5 V supply with powerconsumption of 910 mW with all channels turned on.The ADAR2004 is available in a 7 x 7 mm, 48-terminal LGApackage and is specified from −40 C to +85 C.
