The SIMOPS Low Band Power Amplifier provides powerful VHF/UHF performance across the 30–512 MHz spectrum, delivering up to 50 watts of RF output power in a compact, lightweight 3.2-lb chassis. Built for harsh environments, it maintains full operational capability from -40°C to +60°C, supports 100% duty cycle, and features MIL-STD-1275 and MIL-STD-461 compliance for power and EMI/EMC robustness. With support for widely used waveforms, the Low Band Power Amplifier ensures seamless interoperability across a wide array of platforms and mission sets. Advanced Autosense capabilities and configurable interfaces further simplify integration, enabling rapid deployment across ground, airborne, mobile, and unmanned systems.

Complementing the low-band solution, the SIMOPS High Band Power Amplifier extends coverage into critical upper-frequency channels, operating across both 225–512 MHz and 1250–2600 MHz. Delivering up to 20 watts of continuous RF output power, the High Band unit provides exceptional receive sensitivity with a low noise figure of ≤6 dB. Like its Low Band counterpart, the High Band Power Amplifier is fully ruggedized for extreme environments, offering IP67+ immersion protection, high-vibration tolerance, and comprehensive electrical protections for uninterrupted operation in mission-critical scenarios. Its broad waveform support and intelligent power management ensure high performance across tactical ground communications, UAV platforms, rapid-deployment kits, and fixed infrastructure.

Together, SIMOPS Low Band Power Amplifier and SIMOPS High Band Power Amplifier form a powerful, flexible communications solution that reduces system complexity, and enhances interoperability across diverse mission profiles. Engineered for scalability, ease of integration, and long-term technology evolution, Frontgrade’s SIMOPS Power Amplifiers continue to advance the standard for resilient, multi-domain communications. These new amplifiers position operators to meet the demands of rapidly evolving battlefield networks while ensuring reliable, high-fidelity communications when it matters most.
