The Sunair LPA-9600 is a 1 kW solid-state linear power amplifier engineered for professional and military radio communication systems requiring reliable RF signal amplification across 1.5 MHz to 30 MHz. Operating at 1000 W PEP with selectable power levels of 1 kW or 500 W, the unit delivers continuous-duty performance with intermodulation distortion 36 dB below PEP and harmonic distortion 60 dB below PEP. The amplifier incorporates microprocessor control, redundant internal AC power supplies, and comprehensive BITE diagnostics to LRU level. Band changeover occurs in 10 ms maximum, with 50 Ω unbalanced output impedance and graceful degradation up to 3:1 load VSWR. Modular plug-in construction enables field serviceability and rapid maintenance. The unit integrates directly with Sunair 9000D series radios and operates across −30°C to +65°C. Input requirement is 115/230 VAC ±15%, single phase, 50–60 Hz, drawing 4500 VA typical. Designed and manufactured in the U.S.A., the LPA-9600 is qualified to MIL-STD 810F shock and vibration standards, making it suitable for demanding mobile and fixed-station HF communications platforms.
