Standard SMD Ceramic Bandpass Filter

Customized Standard Cavity Bandpass Filter by Temwell Corporation

Description

Temwell Group provides standard dielectric resonator filters (DR Filters) with SMD (surface mount) packaging design, which can effectively meet the application requirements of a wide range of frequency bands from MHz to GHz. This series of filters has a compact structure, high frequency stability, extremely low insertion loss and excellent out-of-band suppression performance. It can achieve high attenuation filtering effects in a limited space. It is particularly suitable for wireless modules, small base stations, radars, communication equipment, Internet of Things devices and other application scenarios that have dual requirements for filtering accuracy and volume.

Specification Range

  • Frequency band: 400M to 6GHz
  • Bandwidth: DC to 40GHz
  • Impedance: 50 /75 ohm
  • Type: SMD

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.
