Currently, anti‑jamming navigation has been widely adopted in fields such as low‑altitude UAVs, autonomous driving, ports and mines, and power timing, with system requirements for the anti‑jamming capability and noise performance of the RF front‑end continuously increasing.

Bonray introduces RF front‑end solutions for anti‑jamming navigation applications, helping navigation receiver front‑ends achieve high sensitivity and strong interference rejection.

Navigation RF Front‑End Solution

This solution features a core device combination of the ultra‑low insertion loss front‑end limiter BR9737FDJ and ultra‑low noise, high‑linearity LNAs (such as BR9927DAJ, BR9918DAJ, and BR9919DAJ), protecting the receiver front‑end while minimizing noise introduction, thereby assisting customers in efficiently completing device selection and solution implementation for the receiver chain.
