F6212

The F6212 is a 16-channel dual-beam receive active beamforming RFIC multi-chip module designed for 应用 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 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 获得 control resolution spanning 360° and 26dB of dynamic 范围, enabling precise beam pattern and polarization control.

The IC operates from two supply rails of 2.1V–2.5V and 0.95V–1.05V with a typical channel 获得 of 28dB. The chip includes power management 特征 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 范围 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 FC-BGA organic 包裹 with all single-ended 50? matched RF ports and 0.5mm pitch greatly simplifies the physical integration of these devices onto large antenna panels.
