EHF-4CQ1810

RF Directional Couplers are commonly used in radio communications systems. They are passive devices that take in power from existing signals while redirecting these signals to other uses. An RF Directional Coupler, like the EHF-4CQ1810, is designed to allow a signal to pass through from one antenna to another and redirect a portion of the signal to measure its power. This type of coupler is also used to direct power from transmitters to multiple receivers, while at the same time allowing power to be sent from receivers to multiple transmitters.

The EHF-4CQ1810 is a high-frequency directional coupler that is well-suited for a variety of applications, ranging from RF frequency identification (RFID) systems to satellite television signal detection. It has a frequency range of 500MHz to 4GHz, and is designed with a power rating of 30 Watts. The coupler features a four port configuration with an input port, a first output port, a second output port, and an amplitude port.

The EHF-4CQ1810 works by utilizing a bi-directional transmission line circuit with a 4-port network. The input signal is split into two signals, each with different amplitudes. These signals are sent to the first output port and the second output port. The first output port directs a certain amount of the original signal power to the amplitude port, while the second output port typically sends no signal power to the amplitude port.

Having an output port dedicated solely to signal power measurement makes the EHF-4CQ1810 easier to manage and reduces complexity delivered interference. The coupler also has a low insertion loss of less than 0.3dB, helping conserve energy and ensure that a signal’s power is accurately measured. This, combined with its high isolation of 27dB, ensures that signals aren’t disturbed or lost when being measured.

The EHF-4CQ1810 is well suited for a variety of applications, such as cellular tower base station monitoring, redundancy systems, RFID systems, and integrated RF systems. This allows it to be used in a variety of industries, such as telecommunications, automotive, defense, medical, and wireless communications. In these applications, it is used to accurately measure signal power for improved control and performance.

To sum up, the EHF-4CQ1810 is a high-frequency directional coupler that is an ideal choice for a variety of power measurement applications. Its 4-Port design ensures accurate power measurement without sacrificing signal quality, while its low insertion loss, high isolation, and wide frequency range make it a perfect solution for many different industries. The EHF-4CQ1810 is therefore an essential part of any RF system.
