Product Overview 

1.A band-pass Cavity filter is a device that allows a particular frequency band to block other frequencies simultaneously.

2.Center Frequency:580MHz,Insertion Loss:≤0.8dB,VSWR≤1.3,Port Connectors:SMA-Female

3 The filter has the characteristics of low insertion loss, high resistance band rejection

4.With high reliability, stable and reliable working performance 100% brand new and high quality

5.Applications :Test and measurements, Lab use

6.Model Number:04KBF-580/40M-01S

7.The 580MHz RF Cavity Filter is a universal microwave/millimeter wave component, which is a kind of device that allows a particular frequency band to block other frequencies simultaneously. The filter can effectively filter out the frequency point of a specific frequency in the PSU line or the frequency other than the frequency point to obtain a PSU signal of a specific frequency, or eliminate a PSU signal of a specific frequency. Filter is a frequency selection device, which can make specific frequency components in the signal pass through and greatly attenuate other frequency components. Using this frequency selection function of the filter, interference noise or spectrum analysis can be filtered out. In other words, any device or system that can pass specific frequency components in the signal and greatly attenuate or inhibit other frequency components is called a filter.

Key Features



Low insertion loss

Low signal loss results in better SNR in receiver front end and better power delivery to antenna in transmitter

Fast roll-off

Higher selectivity results in better adjacent channel rejection and dynamic range

Wide stopband

Wide spur free band results in better receiver sensitivity

High power handling

Well suited for transmitter application

Protective assembly

Prevents accidental de-tuning of precisely tuned resonant circuit
