Arralis Announces 10W GaN-SiC MMIC K Band HPA
Chipset meets demand for low cost K/Ka band satellite equipment that is simple to interface to digital hardware
Arralis has announced the launch of its new Leonis series GaN-SiC High Power Amplifier (HPA) optimised for satellite downlink communication systems. The HPA operates in K-band from 17.5GHz-20GHz and delivers a saturated power in excess of 10W with typical power added efficiency of 25 percent and large signal gain of 20dB in a compact die size of 3.6×2.9mm.
The part is matched to 50Ω with integrated DC blocking capacitors on RF ports and incorporates an output power detector to assist with system integration. Nominal drain bias is 25V.
The HPA is fabricated on ITAR free, space qualified UMS 0.25um GH25-10 GaN-SiC process. Optimum performance has been achieved at K-band through a combination of UMS device models, NI AWR EDA software and the design expertise of the Arralis MMIC team, according to the company.
“The addition of this latest HPA to Arralis' suite of devices builds on our high-performance K/Ka-band Leonis chipset, forming the final link in the RF power chain and delivering 10W of saturated output power in a compact GaN MMIC” said Thomas Young, senior MMIC design engineer, Arralis. “The new GaN HPA exemplifies the design and application expertise that Arralis provides across a range of mm-wave bands. The data-hungry society of today demands constant, uninterrupted access to information, and this demand will increase in the future. Global connectivity takes a step closer to realisation through the development of this enabling technology for K/Ka Band Satellite Comms”.
The Leonis chipset was developed to meet the needs of the growing demand for low cost K/Ka band satellite equipment that is simple to interface with current digital internet hardware. Applications include 5G communications, airborne high-speed Wi-Fi, low earth orbit mega constellation communications, drone constellations and SAT-Drone-Ground data networks, satellite to automotive connectivity, connected vehicles, last mile and remote internet solutions, IoT and M2M communications.
The part is available as a bare die MMIC or in a preassembled evaluation board.
Arralis is a rapidly scaling company with expertise in RF, micro and millimetre-wave technology. It has offices in Limerick, Ireland and in Belfast, Harwell and Manchester, UK. Its core focus is in E, K/Ka and W band where it has expertise on the highly desirable attenuation window of 94GHz, which allows the development of very high-resolution radar; applications of which include autonomous automotive, helicopter landing, satcomms and massive data rate wireless communications.
