Guerrilla RF Launches GRF2118 with Best-in-Class Noise Figure Across the SatCom X-Band Spectrum

Why It Matters

The GRU2118 gives system designers a COTS solution that dramatically improves receive sensitivity while reducing size and design effort, a critical advantage for cost‑sensitive space and defense programs. Its performance also aligns with upcoming spectrum allocations, extending its relevance as the wireless industry evolves.

Key Takeaways

• 0.57 dB NF, 25.5 dB gain at 7 GHz in low‑bias mode
• 0.67 dB NF, 26.1 dB gain, 19.2 dBm P1dB high‑bias mode
• No external matching needed; 2 × 2 mm QFN‑12 package
• Covers SatCom X‑Band, backhaul, and future 6 GHz 6G bands

Pulse Analysis

The launch of Guerrilla RF’s GRU2118 arrives at a time when the satellite communications market is expanding rapidly, driven by the New Space economy and heightened defense spending. Operators of military and commercial X‑Band satellites demand ever‑lower front‑end noise to maximize link margins, especially for low‑power CubeSat and portable terminal applications. By delivering a sub‑0.6 dB noise figure across the entire 6‑8.5 GHz band, the GRU2118 sets a new benchmark for commercial off‑the‑shelf (COTS) LNAs, offering a performance level previously reserved for bespoke, higher‑cost solutions.

Technically, the GRU2118’s dual‑bias architecture provides designers with flexibility: a low‑current mode (3 V/42 mA) optimizes sensitivity for power‑constrained platforms, while a high‑current mode (5 V/79 mA) supplies the linearity needed in dense, high‑power environments. Its GaAs pHEMT process ensures robust temperature tolerance, and the compact 2 × 2 mm QFN‑12 package eliminates the need for external input or output matching networks, reducing board real‑estate and simplifying RF layout. These attributes translate into faster time‑to‑market and lower total‑cost‑of‑ownership for satellite ground stations, defense receivers, and emerging backhaul radios.

From a business perspective, Guerrilla RF leverages the GRU2118 to strengthen its foothold in high‑growth segments such as 5G/4G infrastructure, automotive telematics, and next‑generation 6G research. The device’s compatibility with both existing X‑Band allocations and the prospective 6 GHz spectrum earmarked for future cellular deployments broadens its addressable market. Coupled with the company’s proven track record—over 200 million devices shipped and repeated Inc. 5000 recognition—the GRU2118 positions Guerrilla RF as a go‑to supplier for cost‑effective, high‑performance RF solutions in an increasingly competitive semiconductor landscape.
