SUCCESS STORY Key Challenges K/Ka-band satcom systems can provide constant, uninterrupted access to information, driving companies to invest heavily in this spectrum for global broadband services. These systems are enabled through high-power amplifiers (HPAs), which form the final link in the RF power chain of next-generation, satellite-based, RF front-end components. Arralis has developed the Leonis chipset, originally as part of the European Space Agency (ESA) Advanced Research in Telecommunications Systems (ARTES) program, to address the growing demand for lower cost K/Ka-band satellite equipment. The chipset includes IQ and subharmonic mixers, upcon- verter and downconverter core chips, switches, phase shifters, low-noise amplifiers (LNAs), and PAs. Within this chipset is the company's LE-Ka1330308, a high-power monolithic microwave integrated circuit (MMIC) amplifier that was fabricated on space-qualified 0.25μm gallium nitride on silicon carbide (GaN on SiC). The three-stage MMIC amplifier was fabricated on the United Monolithic Semiconductors (UMS) GH25-10 process. Arralis has successfully demonstrated transceiver architectures for both uplink and downlink communications.
