RL 100-5 – 50 ohm 10 kW Resistive Load

The RL100-5 is a 50 ohm unbalanced resistive load designed specifically for the HF frequency range 1.5 – 32 MHz.

The load is convection cooled, requires no AC power and is suitable for outdoor unprotected operation. Typical applications include use as a transmitter load, hybrid balancing load and antenna common mode load.

Designed for versatility, the RL100-5 operates seamlessly in various applications within the specified frequency range. Its primary function as a transmitter load makes it an indispensable tool for engineers and operators working on high-frequency transmitters. The load ensures that the transmitter system operates under optimal conditions, allowing for accurate signal transmission and reception.

The RL100-5 serves as a hybrid balancing load, a crucial role in achieving a balanced signal path. By incorporating this load, engineers can fine-tune and optimise the performance of hybrid circuits, ensuring that the signal distribution is evenly balanced between different components. This capability is particularly valuable in applications where precise control over signal balance is essential for maintaining signal integrity and minimising interference.

The adaptability of the RL100-5 extends to its use as an antenna common mode load. In this capacity, the resistive load effectively manages common mode currents in antennas, enhancing overall system performance. This feature is particularly advantageous in outdoor environments where antennas are exposed to diverse weather conditions.
