RFMW announces design and sales support for a half-duplex, transmit/receive integrated circuit. The Renesas F5280 IC is a 4-channel, TRX, half-duplex silicon device using a SiGe BiCMOS process for 28 GHz 5G phased-array applications. The core IC has flexible gain and phase control on each channel to achieve fine beam steering and gain compensation between radiating channels. Designed for 25 to 31GHz operation with fast-beam switching and fast beam-state loading, typical Tx/Rx switching time is 100 ns. Typical gain and phase settling time is 20 ns. The device contains programmable on-chip memory and boasts 3° typical RMS phase error and 0.4 dB typical RMS gain error. Packaged as a small, 3.6 x 3.6 mm BGA.
