EnSilica expands satcoms user terminal portfolio with dual-beam, dual-polarization Ku-band analogue beamformer chipset

Oxford, UK --  May 21, 2025 -- EnSilica, a leading maker of mixed-signal ASICs, has announced two Ku-band beamformer integrated circuits, the ENS92051 and ENS92052, which offer best-in-class power consumption and performance. They are designed to address the needs of the next generation of electronically steered antennas for a range of user terminals used with LEO, MEO and GEO satellite constellations.

The ENS92051 is the dual-beam Ku-band receiver (Rx) supporting eight channels with separate amplitude and phase control. The Rx carrier frequency range is 10.7 to 12.75 GHz with an instantaneous bandwidth of 500 MHz.

The ENS92052 is the Ku-band transmitter supporting eight channels with separate amplitude and phase control. The Tx carrier frequency range 13.75 to 14.5 GHz with an instantaneous bandwidth of 125 MHz.

The eight channels of the chipset can support four dual-polarisation or eight single-polarisation elements.  The highly integrated devices offer low-power and low-cost using phase and amplitude controls with a built-in temperature sensor, and the transmitter has an integral power detector.  The chipset includes a beam table to support very low-latency beam switching and supports a range of power-saving modes.

The device SPI bus and control pins operate from standard 1.8V logic at speeds up to 50 MHz, the core voltage is 1.0 V.  Both chips come in a 63-pin Wafer Level Chip Scale Package.

The devices will be fabricated and tested in Europe, offering customers a European sovereign supply chain. They are designed to meet the requirements of DO-254 DAL 5 and qualified to AEC-Q100 automotive grade 2.

Paul Morris, VP of RF & Communication BU commented:

“The addition of these Ku-band beamformer ICs to our portfolio enables our customers to develop the lowest power user terminals which can connect to existing constellations such as Eutelsat/OneWeb.  They also boost the European supply chain in satellite communications which has become increasingly important in recent months.”

The chipset is available for sampling to lead customers.
