RF Directional Coupler: CPL-5212-20-SMA-79 application field and working principle

The CPL-5212-20-SMA-79 is an RF directional coupler that operates over frequency bands from 3500-3800 MHz, with an average power handling of 10W and VSWR of 1.3:1. This makes it suitable for a variety of radio frequency (RF) applications, and it has been used in many different types of wireless communications systems.

A directional coupler is an important component in any wireless communication system, as it is used to measure the RF power output of the system and ensure it remains within acceptable parameters. The CPL-5212-20-SMA-79 is specifically designed to measure forward and reflected RF power in both transmit and receive applications. It provides a 20 dB coupling factor with low insertion loss, and is capable of accurately measuring RF power in the frequency range of 3500-3800 MHz.

The working principle of the CPL-5212-20-SMA-79 is based on the power divider theory. It works by dividing the input signal power into two branches, and then measuring the amount of power that is coupled from one branch to the other. The power ratio between the two branches is determined by the direction of the RF energy flow, which determines if the relative power is coupled inwards or outwards. By measuring the power in each branch, the power delivered to the output can be accurately measured.

The CPL-5212-20-SMA-79 has been used in a variety of wireless communications applications such as satellite communication systems, Wi-Fi hotspots, cell phone towers, and military communication systems. The directional coupler is able to measure the power output of the system and ensure it remains within acceptable parameters while transmitting or receiving signals. It is also able to detect and identify malfunctioning components in the system. The CPL-5212-20-SMA-79 is a reliable, accurate, and cost effective solution for measuring RF power.

The CPL-5212-20-SMA-79 is a highly reliable and cost effective directional coupler that is well suited for a variety of RF applications. Its low insertion loss and wide frequency range make it suitable for use in most RF systems. With a 20 dB coupling factor and VSWR of 1.3:1, the CPL-5212-20-SMA-79 can accurately measure forward and reflected RF power in both transmit and receive applications, making it an ideal choice for wireless communication systems.
