特性

ADAR3002 is a 17.7 to 21.2 GHz dual beam, 4 element dual polarized beamforming IC for phased array antennas. Each of the 16 RF channels provide a ≥31 dB gain adjustment range and 360 degree phase adjustment, with resolution of less than ≤0.5 dB and 5.625 degrees, respectively, via Variable Amplitude and Phase (VAP) blocks. Each VAP contains a Digital Stepped Attenuator (DSA) and Phase Shifter.

Access to on-chip control registers and memory is through a simple 3-wire or 4-wire serial port interface (SPI). In addition, four address pins allow SPI control of up to 16 devices on the same serial lines. The random access memory (RAM) has storage for up to 256 beamstates, organized into 64 beamstates per polarization per beam. The sequencer selects and advances the beamstate being sourced from either the RAM or the FIFO.

ADAR3002 is available in a 176-ball 6.6 x 6.6 mm Wafer Level Chip Scale Package (WLCSP) and is specified from −40°C to +85°C.
