50W Power Amplifier: Model MOP-PA-2/6G-50W – Comprehensive Technical Overview
Engineered for high-frequency applications, the 50W Power Amplifier Model MOP-PA-2/6G-50W delivers exceptional performance across the 2-6GHz frequency range. This robust module combines high output power with precise controllability, making it ideal for demanding RF communication systems. With reliable temperature compensation, standing wave protection, and advanced monitoring features, it ensures stable operation in diverse environments. Whether you’re integrating into radar systems, wireless infrastructure, or test equipment, this amplifier offers the consistency and durability required for mission-critical tasks.
The amplifier’s design prioritizes both efficiency and safety. A maximum output power of 47±1dBm (approximately 50W) is achieved with a manageable operating current of ≤5A at 28V. Gain stability remains within ±1.5dB across the full temperature range of -10°C to +55°C, ensuring performance doesn’t waver under thermal stress. The inclusion of a dual directional coupler allows for accurate forward power and VSWR monitoring, while the enable switch and power regulation input provide flexible control. For long-term reliability, the module can withstand input power levels up to +10dBm for one minute without damage, and robust protections guard against overheating and reflected power.
