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. The mixer local oscillator (LO) path includes a 4× multiplier requiring an applied LO frequency between 2.4 GHz and 10.1 GHz. 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). The ADAR2004 requires only a single 2.5 V supply with power consumption of 910 mW with all channels turned on. The ADAR2004 is available in a 7 × 7 mm, 48-terminal LGA package and is specified from −40°C to +85°C.
