ADAR2004ACCZ

ADAR2004 is a 4-channel receiver IC that is optimized for millimetre wave body scanning applications. Accepting differential input signals from 10GHz to 40GHz. It provides a low intermediate frequency (IF) output upto 800MHz. Each receive channel also has independent gain control. The mixer local oscillator (LO) path includes a 4× multiplier requiring an applied LO frequency between 2.4GHz and 10.1GHz. The 4× multiplier block includes a programmable filter that helps keep harmonics down before reaching 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 serial peripheral interface (SPI) and are then operated by pulsed inputs (reset and advance). It is used in application such as millimetre wave imaging, security, medical, industrial, multichannel receivers.
