Introducing the 1.55-1.62GHz 50W RF Power Amplifier, a high-performance solid-state module engineered specifically for L-band and GNSS-related applications. Operating across the 1.55GHz to 1.62GHz frequency range, this amplifier leverages advanced GaN HEMT (Gallium Nitride High Electron Mobility Transistor) technology to deliver a powerful 57dBm (50W) continuous wave (CW) output. This makes it an ideal solution for satellite navigation augmentation, telemetry, and specialized communication systems.
This amplifier is designed for mission-critical environments where reliability is non-negotiable. It features a comprehensive built-in protection suite, including over-temperature, over-voltage, under-voltage, and over-current safeguards. With a rugged N-K50 output connector and a standardized D-SUB 7W2 control interface, this module integrates seamlessly into professional RF systems. The unit requires an external cold plate for heat dissipation, ensuring stable operation even under continuous high-power output.
At the heart of this amplifier is a GaN HEMT device. This technology provides significant advantages over traditional silicon or GaAs transistors, including higher power density, superior thermal conductivity, and higher breakdown voltage. The result is a robust amplifier capable of handling high power levels with excellent efficiency, reducing heat generation and improving overall system reliability.
Delivering a 57dBm (50W) CW output, this amplifier provides the high power density required for long-range transmission and signal penetration. With a gain flatness of ±1dB across the 1.55-1.62GHz band, it ensures signal integrity and consistent performance, which is critical for GNSS and satellite communication applications.
Reliability is built into every layer of this design. The module features:
Over-Temperature Protection: Automatically powers off if the temperature exceeds 85°C.
Over-Voltage Protection: Shuts down if the supply voltage exceeds 48V.
Under-Voltage Protection: Shuts down if the supply voltage falls below 36V.
Over-Current Protection: Powers off if the current draw exceeds 50A.
These safeguards prevent catastrophic failure and ensure long-term durability in the field.
The amplifier utilizes a D-SUB 7W2 connector for both power and control, simplifying system integration. The control logic is TTL-compatible:
Pin 4 (Enable): TTL high level turns the amplifier ON.
Pin 5 (Bit): TTL high level indicates normal operation.
This digital interface allows for remote monitoring and management, making it suitable for automated and unmanned stations.
The unit is built for continuous duty. It requires installation on a cold plate for contact heat dissipation, ensuring that the internal components remain within safe operating temperatures. The operating temperature range of -40°C to +60°C makes it suitable for deployment in harsh outdoor environments.
Important Note: The product needs to be installed on a cold plate for contact heat dissipation. This amplifier is designed to transfer heat through its base plate. Proper thermal interfacing (using thermal paste or pads) and a sufficient heat sink or liquid cooling plate are mandatory to maintain the operating temperature within the specified -40°C to +60°C range. Failure to provide adequate cooling may trigger the over-temperature protection or damage the unit.
Comprehensive Protection: The industry-leading protection suite (Over-Temp, Over/Under-Voltage, Over-Current) ensures your investment is safe from power anomalies.
Digital Control: The TTL-compatible D-SUB interface makes it easy to integrate with modern control systems.
High Power Density: Delivering 50W CW in a compact form factor.
Proven Reliability: Designed for continuous operation in demanding environments.
