The ADAR3003 is a 27 to 31 GHz single beam, 4 element dual polarized transmit beamforming IC for phased array antennas. Each of the 4 elements have horizontal and vertical polarization. There are 8 RF channels that provide a ≥31 dB gain adjustment range and 360 degrees of phase adjustment range, 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. Each channel has an integrated RF power detector at its output, with a 30 dB range.

Access of all the 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. Four VAPs’ worth of data is a single beamstate. The random access memory (RAM) has storage for up to 128 beamstates, organized into 64 beamstates per polarization. The on-chip sequencer selects and advances the beamstate being sourced from either the RAM or the FIFO.

The ADAR3003 is available in a 136-ball 5 m × 5 mm Wafer Level Chip Scale Package (WLCSP) and is specified from −40°C to +85°C.
