Description

The F6212 is a 16-channel dual-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 16 (8 per beam) 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,

independent enable controls on every channel, and a single-beam

mode activated via a dedicated control pin. 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.
