10 GHz to 40 GHz, 1:4 Channel, 4 Frequency Multiplier/Filter Data Sheet ADAR2001 FEATURES GENERAL DESCRIPTION The ADAR2001 is a transmitter IC optimized for millimeter 4 input frequency multiplier with programmable harmonic wave body scanning applications. Accepting a single-ended filter Quad differential output PAs with independent enable control continuous wave (CW) input signal between 2.5 GHz and 10 GHz, Input frequency range: 2.5 GHz to 10 GHz the ADAR2001 provides gain, 4 frequency multiplication, Output frequency range: 10 GHz to 40 GHz harmonic filtering, 1:4 signal splitting, and four independently Input power: 20 dBm (50 ) controllable power amplifiers (PAs) with differential outputs Output power: 5 dBm differential (100 ) designed to directly drive dipole antennas with differential inputs. Harmonic rejection: 20 dBc to 40 dBc at all frequencies All device functions and configuration options can be accessed by a 3-wire or 4-wire SPI control of all functions 3-wire or 4-wire Analog Devices, Inc., serial peripheral interface On-chip programmable state machines for fast (SPI). multiplier/filter and transmitter switching and control Two state machines are also integrated into the ADAR2001, On-chip temperature sensor, output power detectors, and ADC DC power: 450 mW (2.5 V supply) which facilitate easy configuration, control, and fast switching 6 mm 6 mm, 40-terminal LGA package of the frequency multiplier, filter, and transmitter sections. These sequencers are programmed through the SPI and are APPLICATIONS then operated by pulsed inputs (reset and advance). Millimeter wave imaging The output power and chip temperature can be monitored by Security four on-chip detectors and a temperature sensor whose outputs Medical are multiplexed to an 8-bit ADC. Industrial The ADAR2001 requires only a single 2.5 V supply with power Wideband local oscillator (LO) multiplier/distributor 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 40C to +85C.
