8-Ch Tx Active Beamforming IC
13.75 – 14.5 GHz
F6521
Short-Form Datasheet
Description
The F6521 is an 8-channel transmit active beamforming RFIC
designed for application in Ku-band SATCOM planar phased array
antennas. The IC has a single common RF input port and eight
output channels. The eight independently controlled output
channels can drive eight single-polarized elements or four dual-
polarized elements of an electronically scanned array (ESA). Each
channel has 6 bits of digital phase control covering 360° and 25dB
of gain control with a minimum step size of 0.2dB, enabling precise
beam pattern and polarization control.
Operating from a single supply of 2.1 - 2.5V, the RFIC has 28dB of
nominal small signal gain with a typical P1dB of 10.5dBm per
channel. The F6521 is highly efficient and features a low power
standby mode as well as independent enable controls on every
channel. The device’s SPI bus and control pins operate from
standard 1.8V logic at speeds up to 50MHz. Advanced digital
modes and large on-chip memory allows for < 100ns beam position
switching times at the array level, greatly reducing dead time and
latency.
Finally, the compact and CTE-matched FC-BGA organic package
with all single-ended 50ohm matched RF ports greatly simplifies
the physical integration of the F6521 onto large antenna panels.
