Buy High quality Band 3 Duplexer Cavity Companies – RF 898.5MHz-937.5MHz SMA-Female Cavity Duplexer – Keenlion Detail:
Product Overview
The 898.5MHz-937.5MHz 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.
Duplexer, also known as antenna commoner, is a special bidirectional three terminal filter. The duplexer should not only couple the weak reception signal, but also feed the large transmission power to the antenna, and the two are required to complete their functions without mutual influence. The general duplexer is composed of a spiral vibration cavity. Due to its high working frequency and great influence of distribution parameters, it is often made into a sealing sleeve. Each signal feeder is made of coaxial cable with good shielding effect. The cavity shape material also requires a certain degree of finish. In order to facilitate heat dissipation, the appearance is often black. The three signal ends generally use standard high-frequency connectors Q9 ￠ or L16 ￠ high-frequency sockets.
Duplexer is the main accessory of different frequency duplex radio station and relay station. Its function is to isolate the transmitting and receiving signals to ensure that the receiving and transmitting can work normally at the same time. It is composed of two groups of stopband filters with different frequencies to avoid the transmission of local transmitted signals to the receiver.
