Data Sheet

ADAR1000

8 GHz to 16 GHz, 4-Channel, X Band and Ku Band Beamformer

FEATURES

GENERAL DESCRIPTION

► 8 GHz to 16 GHz frequency range

► Half-duplex for transmit and receive modes

► Single-pin transmit and receive control

► 360° phase adjustment range

► 2.8° phase resolution

► ≥31 dB gain adjustment range

The ADAR1000 is a 4-channel, X and Ku frequency band, beam-

forming core chip for phased arrays. This device operates in half-

duplex between receive and transmit modes. In receive mode, input

signals pass through four receive channels and are combined and

output at the common RF_IO pin. In transmit mode, the RF_IO

input signal is split and passes through the four transmit channels.

In both modes, the ADAR1000 provides a ≥31 dB gain adjustment

range and a full 360° phase adjustment range in each radio fre-

quency (RF) channel, with 6-bit resolution (less than ≤0.5 dB and

2.8°, respectively).

► ≤0.5 dB gain resolution

► Bias and control for external transmit and receive modules

► Memory for 121 prestored beam positions

► Four −20 dBm to +10 dBm power detectors

► Integrated temperature sensor

► Integrated 8-bit ADC for power detectors and temperature sen-

sor

A simple 4-wire serial port interface (SPI) controls all of the on-chip

registers. In addition, two address pins allow SPI control of up

to four devices on the same serial lines. Dedicated transmit and

receive load pins also provide synchronization of all ADAR1000

chips in the same array, and a single pin controls fast switching

between the transmit and receive modes.

► Programmable bias modes

► 4-wire SPI interface

The ADAR1000 is fabricated in a silicon-germanium, bipolar CMOS

(BiCMOS) process. The device is available in a compact, 88-termi-

nal, 7 mm × 7 mm, LGA package and is specified from −40°C to

+85°C.

APPLICATIONS

► Phased array radar

► Satellite communications systems
