EnSilica has announced two Ku-band beamformer ICs, the ENS92051 and ENS92052, designed to meet the needs of the next generation of electronically steered antennas for a range of user terminals used with LEO, MEO, and GEO satellite constellations.
Fabricated and tested in Europe, the Ku beamformer ICs offer customers a European sovereign supply chain. They are designed to meet the requirements of DO-254 DAL 5 and qualified for AEC-Q100 automotive grade 2.
The ENS92051 is a dual-beam Ku-band receiver (Rx) that supports 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 chipset offers best-in-class power consumption and performance.
The ENS92052 is a Ku-band transmitter that supports eight channels with separate amplitude and phase control. The Tx carrier frequency ranges from 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 cost, utilising phase and amplitude controls with a built-in temperature sensor, and the transmitter features an integral power detector. The chipset includes a beam table to facilitate very low-latency beam switching and offers a range of power-saving modes.
The SPI bus and control pins of the devices operate at standard 1.8 V logic with speeds reaching up to 50 MHz, while the core voltage is 1.0 V. Both chips come in a 63-pin Wafer Level Chip Scale Package.
Paul Morris, VP of RF and 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.
