Standard Waveguide Filter

Customized Standard Cavity Bandpass Filter by Temwell Corporation

Description

Temwell Group provides standard waveguide band pass filters designed for 4GHz band applications, covering a center frequency of approximately 4GHz and with a passband coverage of 500MHz, which can effectively support medium frequency to high frequency RF communication systems. This series of filters is made of precision waveguide structure, with extremely low insertion loss and excellent frequency stability. In particular, it has high attenuation performance in out-of-band suppression, which can greatly reduce noise and interference in adjacent frequency bands and improve the signal purity and communication efficiency of the overall system. It is widely used in high-frequency and rigorous fields such as radar, wireless base stations, test instruments, and satellite ground stations.

Specification Range

  • Frequency band: to 10GHz
  • Bandwidth: 500MHz
  • Impedance: 50 /75 ohm

Series Feature

All standard items are mature models with completed designs. Orders can be placed at any time and put into production quickly. The average delivery time is only 7 to 14 days, which greatly improves project development efficiency and procurement convenience. The product also supports a variety of connector support, making it easier to integrate into different system architectures and enhancing the flexibility of practical use.
