UHF Mobile Duplexer 380-400MHz, 406-440MHz, 480-512MHz


As Christmas approaches, we must deliver the products today. Due to an increasing number of parts suppliers ceasing production, our delivery cycle has become longer. Our American customers have been waiting for almost a month, and we sincerely apologize for the delay. However, we are pleased to announce that we quickly found a solution. Even with rising costs, our wholesale prices remain unaffected by this factor. In fact, our prices have always been largely unaffected by external factors. Our customers are primarily long-standing ones, with some collaborating for 1-2 years, 5-6 years, or even 10 years. They are crucial to us, and over the years, they have supported us and provided valuable advice, aiding us in continually improving our product craftsmanship. As Christmas approaches, we extend our blessings to everyone.

About UHF mobile duplexer

A UHF mobile duplexer is a device used in radio communication systems, particularly in mobile radio systems. The purpose of a duplexer is to enable a single to be used for both transmitting and receiving signals on a specific frequency band. This is crucial in mobile communication, where space and weight constraints make it impractical to use separate antennas for transmission and reception.

The frequency range of a UHF mobile duplexer is typically within the UHF band, which spans from 300 MHz to 3 GHz. The specific frequency range of a duplexer depends on the UHF band it is designed for. In mobile communication, UHF frequencies are commonly used for two-way radio communication, such as in public safety radios, business radios, amateur radio, and other wireless communication systems.

The duplexer ensures that the transmitter and receiver can operate simultaneously without interfering with each other. It achieves this by allowing signals in the transmit band to pass from the transmitter to the antenna while blocking or attenuating signals from the receiver in the same band. Conversely, it allows signals in the receive band to pass from the antenna to the receiver while blocking or attenuating signals from the transmitter in that band.
