RF Duplexer
A cavity duplexer is a special type of duplexer used in wireless communication systems to separate transmitted and received signals in the frequency domain. The cavity duplexer consists of a pair of resonant cavities, each specifically responsible for communication in one direction.
The working principle of a cavity duplexer is based on frequency selectivity, which uses a specific resonant cavity to selectively transmit signals within the frequency range. Specifically, when a signal is sent into a cavity duplexer, it is transmitted to a specific resonant cavity and amplified and transmitted at the resonant frequency of that cavity. At the same time, the received signal remains in another resonant cavity and will not be transmitted or interfered with.

RFTYT RF Hybrid Combiner Signal combination and Amplification
RF hybrid combiner, as a key component of wireless communication systems and radar and other RF electronic devices, has been widely used. Its main function is to mix input RF signals and output new mixed signals.RF Hybrid Combiner has the characteristics of low loss, small standing wave, high isolation, good amplitude and phase balance, and multiple inputs and outputs.
RF Hybrid Combiner is its ability to achieve isolation between input signals. This means that the two input signals will not interfere with each other. This isolation is very important for wireless communication systems and RF power amplifiers, as it can effectively prevent signal cross interference and power loss.

RFTYT Low PIM Couplers Combined or Open Circuit
Low intermodulation coupler is a device widely used in wireless communication systems to reduce intermodulation distortion in wireless devices. Intermodulation distortion refers to the phenomenon where multiple signals pass through a nonlinear system at the same time, resulting in the appearance of non existing frequency components that interfere with other frequency components, leading to a decrease in wireless system performance.
In wireless communication systems, low intermodulation couplers are usually used to separate the input high-power signal from the output signal to reduce intermodulation distortion.

RF Coupler (3dB, 10dB, 20dB, 30dB)
A coupler is a commonly used RF microwave device used to proportionally distribute input signals to multiple output ports, with output signals from each port having different amplitudes and phases. It is widely used in wireless communication systems, radar systems, microwave measurement equipment, and other fields.
Couplers can be divided into two types according to their structure: microstrip and cavity. The interior of the microstrip coupler is mainly composed of a coupling network composed of two microstrip lines, while the interior of the cavity coupler is just composed of two metal strips.
