+**Design of a K-Band MMIC PA for Satcom Applications**

+K/Ka-band (26.5-40 GHz) satellite communications (satcom) systems are popular for global broadband services, offering universal access to faster data rates due to the higher bandwidths available in this frequency spectrum. These systems are enabled through high-power amplifiers (HPAs) in next-generation, satellite-based, RF frontend components. Originally part of the European Space Agency (ESA) Advanced Research in Telecommunications Systems (ARTES) program, Arralis Ltd. in Limerick, Ireland, has developed the Leonis chipset to meet the growing demand for lower cost K/Ka-band satellite communications (satcom) equipment. This article describes the design of the Leonis chipset using the Cadence AWR Design Environment® platform. The chipset includes in-phase quadrature (I/Q) and subharmonic mixers, upconverter 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. Arralis has successfully demonstrated transceiver architectures for both uplink and downlink communications.
