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 SAT planar phased array antennas. The IC has a single mon RF input port and eight output channels. The eight independently controlled output channels can drive eight single-polarized elements or four dualpolarized elements of an electronically scanned array (ESA). Each channel has 6 bits of digital phase control covering 360° and 25d B of gain control with a minimum step size of 0.2d B, enabling precise beam pattern and polarization control. Operating from a single supply of 2.1 - 2.5V, the RFIC has 28d B of nominal small signal gain with a typical P1d B of 10.5d Bm 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 pact 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.
