The F6123 is a 16-channel dual-beam receive active beamforming RFIC designed for application in Ku/CDL-Band 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 may 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 a single supply of 2.1V–2.5V. When paired with the Renesas F6923 LNA, it achieves a nominal cascaded gain of 30dB, while minimizing the front end feed loss due to the flexibility of LNA physical placement near the antenna feeds.
