Cavity Filter

We mainly provide bandpass cavity filter covering 500MHz to 26.5GHz with full product series, which features stable and reliable temperature performance, most optimized outer size and various input/output to offer customers the biggest convenience for system integration.

General Capability:

· full coverage:100MHz~26.5GHz
· passband VSWR≤1.2：1
· 1dB relative bandwidth：0.3~50%
· input/output impedance：50Ω
· number of sections：3~13
· average power: 10~300W
· working temperature：-45℃ ~ +85℃

Main design technology：

Comb filter、interdigital filter and coaxial resonant cavity filter

Features and advantage:

· 1/8 wavelength design, making the size as small as possible
· adopt flexible design plan based on the requirement on the structure and  performance
· high suppression design for the low order extraneous passband, putting the extraneous passband 5 octaves away.
· flexible input/output type, convenient for circuit design and connection.

Input/output:

Standard SMA or removable connector (default)

Or various PIN type, which could be soldered onto the PCB and therefore enabling the size of assembly and subsystem as small as possible.

At present, our products are mainly customized. There are some examples as below, and more specifications are available or customizable.
