Description

The F6202 is an 8-channel single-beam receive active

beamforming RFIC multi-chip module designed for application in

Ka-Band SATCOM planar phased array antennas. The IC has

eight RF input ports, two RF output ports and eight

phase/amplitude control channels. The eight input ports of the IC

can be driven by eight single-polarized elements, or four dual-

polarized elements of an electronically scanned array (ESA). Each

channel has 6 bits of digital phase and gain control resolution

spanning 360° and 26dB of dynamic range, enabling precise beam

pattern and polarization control.

The IC operates from two supply rails of 2.1 - 2.5V and 0.95 - 1.05V

with a typical channel gain of 28dB. The chip includes power

management features such as a low-power standby mode, and

independent enable controls on every channel. An integrated Hi-Q

bandpass filter provides rejection of SATCOM Tx and 5G mmWave

signals, improving the dynamic range without additional power

consumption. The device SPI bus and control pins operate from

standard 1.8V logic at speeds up to 50MHz. Advanced digital

modes and large on-chip memory allow for < 100ns beam position

switching times at the array level, greatly reducing dead time and

latency.

Finally, the compact and CTE-matched FCBGA organic package

with all single-ended 50ohm matched RF ports and 0.5mm pitch

greatly simplifies the physical integration of these devices onto

large antenna panels.
