Introduction to RF Directional Coupler

An RF directional coupler is a passive, three-port device commonly used in radar and communications systems to measure the instantaneous value of RF input power and/or to sample a known portion of incident RF power for testing, monitoring, or control purposes. It is connected between two points in an RF transmission line in order to measure the forward and/or reverse power. The device is usually small and lightweight and is usually characterized by its coupling coefficient, directivity, frequency range, insertion loss, and power handling capability. A typical RF directional coupler consists of two coils, a pair of directional bridges, a pair of transformers linking them, and a sample port. The primary purpose of such a device is to sample a portion of the forward wave (from port 1 to port 2) or the reverse wave (from port 2 to port 1). The sampled portion is conducted to the sample port for measurements or for control purposes.

DC3338J5005AHF Directional Coupler

The DC3338J5005AHF directional coupler is a straight-through (1-2) type 3-port directional coupler based on a mems-based DPTF called “mRotator” technology developed by Samsung. This directional coupler has a high coupling coefficient of 20dB and a high port-to-port isolation of 40dB @ 6GHz. It also has a high frequency range of DC-6GHz and a high power handling of 20W.This directional coupler consists of two RF switching modules connected by a metal enclosure. To increase isolation and to control the directivity performance, each module includes resistive elements and capacitors. This directional coupler is designed to have a low profile and low insertion loss and is ideal for use in wireless applications.

DC3338J5005AHF Application Field and Working Principle

The DC3338J5005AHF directional coupler is suitable for use in a range of applications, such as Wi-Fi and mobile communication, as well as military, avionic, automotive, medical, satellite, and land-mobile radio systems. It can be used in power dividing, power measuring, and antenna switching applications, as well as for signal testing and sampling in laboratory and manufacturing environments.The working principle of a DC3338J5005AHF directional coupler is based on the simultaneous passing of two waves: a forward wave and a reverse wave. The forward wave passes through port 1 to port 2, while the reverse wave passes through port 2 to port 1. The ratio of the two waves (the coupling coefficient) is measured and the sample port is used to measure the forward or reverse wave. The directivity of the device is determined by the separation between two sections of the directional coupler (port 1 and port 2). The higher the separation, the higher the directivity. In summary, the DC3338J5005AHF directional coupler is a reliable and high-performance three-port device suitable for a range of applications. It is characterized by its high coupling coefficient, high port-to-port isolation, high frequency range, low insertion loss, and high power handling capability. This RF device is commonly used for power dividing, power measuring, antenna switching, signal testing and sampling, as well as for use in Wi-Fi, mobile communication, military, avionic, automotive, medical, satellite, and land-mobile radio systems.
