The EHF-FD1548 is an RF Directional Coupler that operates in the range of 15-48 GHz. It provides low insertion loss, high isolation, wideband capabilities, and features a flat frequency response. This device is ideal for military applications, where performance and reliability are paramount. The EHF-FD1548 features a hermetically sealed aluminum housing, allowing it to be used in harsh operating environments.

The EHF-FD1548 is manufactured using the latest state-of-the-art fabrication techniques and features an outstanding power handling capability of up to 5 kW incident power. Built-in temperature compensation ensures accuracy and stability over the wide temperature range of -55 to +85°C.

The EHF-FD1548 utilizes a balanced 3-port design that provides an excellent phase matching accuracy of 2 degrees. This device also provides an excellent VSWR of 1.5 to 1 over the entire frequency range. Additionally, the EHF-FD1548 provides excellent power loss and low insertion loss at all frequencies.

The working principle of the EHF-FD1548 is based on the law of reflection. When an incident wave strikes the inner wall of the RF directional coupling device, part of the wave is reflected, while part of the wave passes into the device. The inner wall is designed to maintain a constant impedance, so that the phase and amplitude of the reflected wave are the same as the incident wave. This process provides a path for signals to be transferred between the input and output ports of the device.

The EHF-FD1548 is ideal for use in a variety of applications, including antenna systems, microwave links, radar systems, and test & measurement equipment. It can be used as a power divider, directional coupler, hybrid coupler, or as a simple isolation component. Additionally, the EHF-FD1548 can also be used as an analog signal path splitter, allowing signals to be routed from one port to multiple outputs.

The EHF-FD1548 is an excellent choice for applications that demand accurate and reliable performance. It features low insertion loss, high isolation, and wideband capabilities, making it ideal for a variety of military and commercial applications.
