RF cavity filters for 5G

30 May 2022 Telecoms, Datacoms, Wireless, IoT

RF 5G cavity filters are one of the various types of radio frequency filters, a basic component of modern communication systems, and one of the four most common filters in the current generation. They are a type of resonant filter, which are most commonly made up of a metal resonator with a metal shell and thick metal coil. Multiple metal resonators are used to form a cavity filter.

Because of its large size and solid structure, the RF cavity filter can be operated reliably in harsh environments for many years. Also, it can withstand high-power signals, so it is very suitable for communication applications from 10 MHz to 10 GHz. At lower frequencies, the cavity is large and the internal cable is longer, while at higher frequencies, the cavity volume will be reduced. The function of the 5G RF cavity filter is to pass or reject the RF signal in the specified frequency range.

There are usually four types of RF filter: band-pass, high-pass filter, low-pass and band-stop. They are typically used in base stations, high-power transmitters, cellular tower communication and satellite communication.

Based on over 25 years of experience, Temwell has established a one-stop service for 5G RF cavity filters, featuring high specifications across a wide range of power requirements. Models include high-pass cavity filters, low-pass cavity filters, RF cavity filters, band-stop cavity filters and cavity notch filters. The company’s customer service accommodates frequency and bandwidth changes, attenuation value requests, size changes, impedance changes, connector types, group delays, power levels and more.
