17~21.5GHz 16 Channel Dual-Beam RX Beamformer ZRF8366 Designed for Application in K-Band Planar Phased Array Antennas

PublishTime： 2024-03-14 Article Source：ZIRO

The ZRF8366 16 Channel Dual-Beam RX Beamformer is a dual-beam receive active beamforming RFIC designed for application in K-Band planar phased array antennas. The IC has eight RF input ports, two RF output ports, and 16 (8 per beam) phase/amplitude control channels. The eight input ports of the device can be driven by eight single-polarized elements, or four dual-polarized antenna elements. The device integrated an 8-bit ADC for sampling the output of the temperature sensor. The chip features ESD protection on all pins.

Control of all the on-chip registers is through a simple 4-wire serial port interface (SPI). In addition, three address pins allow SPI control of up to 8 devices on the same serial lines.
