XMC0204P2-30G

RF Directional Coupler is used to measure signal strength of radio frequency communication systems, radar and radio navigation systems. The XMC0204P2-30G belongs to the family of wide-range Directional Couplers.

General Introduction

The XMC0204P2-30G is a wideband coupler with a coupling factor of 30±1 dB. It is a four-port RF power divider (splitter) with port-to-port isolation in excess of 40 dB. This unit has low insertion loss (overall 0.4dB) and insertion phase (over 140 dB) over the entire operating bandwidth. It also features very good return loss (VSWR 1:1.2) and good dynamic range, making it suitable for many applications requiring precise signal coupling and power measurements for frequencies up to the gigahertz range.

Function Principle

The XMC0204P-30G RF Directional Coupler has two main components – the directional coupler and an attenuator. The directional coupler works by splitting the input signal into two parts – a forward signal (1-2) and a reflected signal (1-3). The reflected signal is then passed through the attenuator before being re-routed back to port 1, producing an output signal at port 4. This output signal is substantially lower in magnitude than the incoming signal and has a certain phase shift relative to the incoming signal.

In some applications, the phase shift can be used to determine impedance of the system at a certain frequency, or to measure the power ratio between input and output signals. In other applications, the coupled output signal can be used as a reference signal for diversity antenna systems, radar systems, filtering systems, and more.

Application Field

The XMC0204P2-30G is suitable for a range of applications including directional antenna systems, radio and microwave test instrumentation, cellular base stations and radio links. It can also be used for high power measuring applications, especially where low insertion loss is required, such as filtering systems, Wi-Fi systems and microwave transmission systems. As this RF Directional Coupler is a wideband device it can be used for frequency bands up to the gigahertz range. It is also a good coupler for radar systems where frequency of operation changes with time or distance.

Conclusion

The XMC0204P2-30G is a highly reliable and accurate RF Directional Coupler. Its wide-range operating band allows it to be used for many applications, from low power measurements to high power applications. It\'s small size and light weight make it ideal for portable and remote applications. With its low insertion loss and insertion phase, it can be used as a reference signal for many applications where accurate signal measurement is required.
