Standard Low band Cavity Filter

Customized Standard Cavity Bandpass Filter by Temwell Corporation

Description

Temwell Group provides standard Band Pass Filters (BPF) covering a low frequency band from 400MHz to 28GHz, which can flexibly meet diverse application requirements. This series of filters can support narrow bandwidth design (20-50MHz) and can also provide a wide bandwidth range of at least 100MHz, suitable for precise frequency selection and broadband applications. The product also has an out-of-band suppression capability of more than 60dB, which can significantly reduce noise interference and support high power handling requirements, with a maximum power tolerance of up to 100W. It is particularly suitable for radar systems, wireless communications, test equipment, power modules, military equipment and other scenarios with strict requirements on frequency stability and power tolerance.

Specification Range

  • Frequency band: DC to 60GHz
  • Bandwidth: 1MHz to 40GHz
  • Type: N, SMA, SMD, Needle as SMD, etc
  • Power: up to 200 watts.
  • 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.
