1.8 – 6 GHz
1.8 – 6 GHz coverage — radar, EW, and microwave data links.
Exploded view — 3-board PCB stack
Ruggedised enclosure — QSR-LM-FEM-EC
Full Tx/Rx path from SDR through power, filtering, and antenna interface.
Individual boards ship as bare PCBs (Open Card). The full series ships as one ruggedised, enclosed assembly — QSR-LM-FEM-EC.
SDR-side Tx/Rx conditioning with switched BPF banks
SDR-side board: switched BPF filter bank, DSA, LNA, driver amp, simplex/duplex switch, and limiter. Four Rx BPF bands and four Tx LPF bands cover the full 1.8 – 6 GHz range.
Key blocks
Tx amplification, coupling, Tx/Rx routing
Internal 5 W PA, directional coupler, and T/R switch. Drives external PAs up to 20 W for microwave data links and EW transmitters.
Key blocks
Final-stage harmonic rejection on the antenna interface
Four-band switched LPF filter bank for harmonic rejection on the PA output. Suppresses unwanted emissions before they hit the antenna.
