The F6103 is an 8-element receiver silicon IC designed using a SiGe BiCMOS process for 14GHz to 16GHz SATCOM, Weather Radar, Test and Measurement and other phased array applications. The core IC has 6-bit phase control coupled with 30dB gain control on each channel to achieve fine beam steering and gain compensation between radiating elements. The device has 17dB nominal electric gain and -31dBm IP1dB. The core chip achieves an RMS phase error of 3° and RMS gain error of 0.3dB over the frequency of operation.

The chip operates at 2.1 to 2.5 V and features ESD protection on all pins. The core design includes standard SPI protocol that operates up 50MHz with fast-beam switching, fast beam-state loading and fast four on-chip beam storage. The module has four external bias pins (5-bit DACs) to control external LNA’s, temperature reporting and external biasing.
