RF Directional Couplers are electrical components used in radio-frequency (RF) systems to balance transmission and reception of a desired signal. The HDH-01503GHD(40) is an RF directional coupler designed for industrial or laboratory use. It is a high-power, low-noise device with a wide operating frequency range.

Application Field

The HDH-01503GHD(40) can be used for a variety of applications, including distributed antenna systems (DAS), wireless local area networks (WLANs), cellular networks, and satellite networks. It is also suitable for laboratory testing and characterization. The device\'s low noise figure, high power handling capability, and uniform frequency response make it a reliable selection for wireless communications.

Working Principle

A directional coupler works by coupling a small fraction of a signal traveling in one direction in a transmission line, and transferring it in the opposite direction. This is achieved by using an arrangement of two loops of a transmission line connected to a common port. The port on the left side is the input port and the port on the right side is the output port, with the common port in the middle. The waves incoming to the left side are split between the two loops and a portion of the signal is transferred to the right side. The output signal amplitude is proportional to the input signal amplitude.

The HDH-01503GHD(40) directional coupler is designed with an impedance of 50 Ohms and a maximum VSWR of 1.3:1. It offers a wide operating frequency range, from 0.45 to 3.6 GHz, with low insertion loss and high directivity. The coupler also features a low noise figure of 0.5 dB, a maximum input power of 10 W, and an operating temperature range of -55 to +85°C. It is designed to meet the standard requirements of MIL-STD-810F.

In addition to its wide frequency range, the device also has a high power handling capacity of 40 Watts, making it an ideal choice for high-end applications. With its superior performance characteristics, the HDH-01503GHD(40) is an excellent choice for any system requiring reliable and repeatable performance.

The HDH-01503GHD(40) directional coupler is an excellent choice for a wide range of applications in today\'s wireless environment.
