High Gain 8-12GHz 100W GaN Broadband SSPA Module

This SSPA is a broadband module designed as a 8-12GHz power amplifier delivering 100W typical saturated output power across a wide frequency range fully covering the entire 8‑12 GHz band. With a high power gain of 50 dB and gain flatness within ±1 dB, it ensures consistent performance over the full band. The GaN‑based design and chip‑and‑wire assembly technology provide state‑of‑the‑art efficiency and an excellent power‑to‑volume ratio. The SSPA features 50‑ohm input and output matching, with input return loss better than –10 dB. Harmonic emissions are below –50 dBc and spurious signals below –60 dBc, making this broadband module ideal for clean signal amplification in demanding environments. At 100W output, power‑added efficiency typically ranges from 22% to 30%. The built‑in protection circuits monitor temperature and current: over‑temperature alarm triggers at 85°C ±5°C and shuts down the module, with automatic restart when cooled below 65°C; over‑current alarm activates if current exceeds 20 A for 5 seconds, then the module shuts down and requires a manual power cycle to resume. This 8-12GHz power amplifier operates from a 28 VDC supply with a quiescent current of 8.1 A and a dynamic current of 15.5 A at 100W output. The module is housed in a compact enclosure measuring 160 × 120 × 25 mm and weighing only 2.0 kg. RF input uses an SMA female connector, and output uses an N‑K female connector. Environmental ratings include an operating temperature range of –20 to 50°C, storage from –25 to 65°C, and non‑condensing humidity up to 95%. With its rugged design and comprehensive protections, this broadband module is perfectly suited for jamming, EMC testing, and measurement applications where high power and reliability are paramount. In summary, the SSPA delivers exceptional performance as a 8-12GHz power amplifier with 100W output and wide bandwidth, all in a compact and reliable package.
