Ka-Band SATCOM Transmit SiGe IC

The F6502 is an 8-element transmitter silicon IC designed using a SiGe BiCMOS process for Ka-Band SATCOM (27 to 31GHz) phased array applications. The core IC has 6-bit phase control coupled with more than 35dB gain control on each channel to achieve fine beam steering and gain compensation between radiating elements. The device has 24dB nominal gain and 13dBm OP1dB. 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 2.1V 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.
