The ADAR2004 from Analog Devices is a 4-Channel Receiver Mixer with an RF frequency from 10 to 40 GHz, an LO frequency of 2.4 to 10.1 GHz, and an IF frequency from 0 to 800 MHz. It has a gain range from 21 to 41 dB with a noise figure of less than 11 dB and an input P1dB of -20 dBm.
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 an SPI Interface and are then operated by pulsed inputs (reset and advance). It requires a single 2.5 V supply and consumes 910 mW of power. The ADAR2004 is available in a 48-terminal LGA package that measures 7 x 7 mm and is suitable for applications such as millimeter-wave imaging (security, medical, industrial) and multichannel receivers.
