mmWave Loss and Unstable Performance in a Satellite Payload

Challenge

While developing a next‑generation Ka‑band and W‑band satellite payload for a low‑Earth‑orbit communications constellation, an RF systems engineer encountered an unexpected challenge. Although the team designed a GaN power amplifier and low‑noise receiver chain to operate above 80 GHz, system testing revealed significant performance degradation. The active devices met their specifications, but once the signal left the die, system performance collapsed: Insertion loss exceeded the link budget by 1.5 dB Parasitic inductance from wire bonds and interconnects distorted matching Board-to-board variation caused gain and phase inconsistencies across flight units Commercial passive components were too large and introduced resonances above 70 GHz The design relied on an advanced organic PCB with thick‑film passives and LTCC modules. Despite extensive tuning and redesign cycles, performance drifted from build to build, introducing unacceptable risk to schedule and qualification.
