Best Duplexer 2m 70cm Service – N-Female Duplexer RF 410-415MHz /420-425MHz Duplexer Hybrid Coupler / Combiner for Radio Repeater – Keenlion
Best Duplexer 2m 70cm Service – N-Female Duplexer RF 410-415MHz /420-425MHz Duplexer Hybrid Coupler / Combiner for Radio Repeater – Keenlion Detail:
Product Overview
The 410-415MHz /420-425MHz Cavity duplexer is a universal microwave/millimeter wave component,Its function is to isolate the transmitting and receiving signals to ensure that both receiving and transmitting can work normally at the same time. It is composed of two sets of filters with different frequencies to prevent the signal transmitted by the machine from transmitting to the receiver. The general Duplexer is composed of spiral vibration cavity. Due to its high working frequency and great influence of distribution parameters, it is often made into a sealed sleeve, each signal feeder uses coaxial cable cavity with good shielding effect and requires a certain degree of smoothness. In order to facilitate heat dissipation, the appearance is usually black. Duplexer is used for mobile communication and working as an unattended transfer station in the field.
Typical applications
It has a good function of frequency selection and filtering in circuits and electronic high-frequency systems, and can suppress useless signals and noise outside the frequency band
It is used in aviation, aerospace, radar, communication, electronic countermeasure, radio and television and various electronic test equipment
When using, pay attention to the good grounding of the shell, otherwise it will affect the out of band suppression and flatness index
