The ADAR2001 is a transmitter IC optimized for millimeter wave body scanning applications. Accepting a single-ended continuous wave (CW) input signal between 2.5 GHz and 10 GHz, the ADAR2001 provides gain, 4? frequency multiplication, harmonic filtering, 1:4 signal splitting, and four independently controllable power amplifiers (PAs) with differential outputs designed to directly drive dipole antennas with differential inputs.All device functions and configuration options can be accessed by a 3-wire or 4-wire Analog Devices, Inc., serial peripheral interface (SPI).Two state machines are also integrated into the ADAR2001, which facilitate easy configuration, control, and fast switching of the frequency multiplier, filter, and transmitter sections. These sequencers are programmed through the SPI and are then operated by pulsed inputs (reset and advance).The output power and chip temperature can be monitored by four on-chip detectors and a temperature sensor whose outputs are multiplexed to an 8-bit ADC. The ADAR2001 requires only a single 2.5 V supply with power consumption of 450 mW with one channel turned on.The ADAR2001 is available in a compact, 40-terminal, 6 mm ? 6 mm LGA package and is specified from ?40?C to +85?C.APPLICATIONS Millimeter Wave Imaging Security Medical Industrial Wideband local oscillator (LO) multiplier/distributor
