1420–1530MHz RF Band Pass Cavity Filter

50W RF Power Handling | Low Insertion Loss | SMA-K Connectors

Overview

The 1420–1530MHz RF Band Pass Cavity Filter is designed for wireless communication systems that require precise frequency selection and effective suppression of unwanted signals. It allows RF signals within the specified passband to pass through while attenuating signals outside the operating frequency range.

With an insertion loss of ≤0.8dB, a VSWR of ≤1.5, and maximum input power handling of 50W, this cavity filter is suitable for integration into RF transmitters, receivers, wireless communication equipment, and RF front-end systems.

Its compact metal housing measures 61 × 51 × 17mm, making it convenient for space-constrained equipment designs. Custom frequency ranges, bandwidths, attenuation requirements, and mechanical configurations can be discussed for specialized projects.

FAQ

Q1: What is the operating frequency range of this filter?

The standard configuration operates from 1420MHz to 1530MHz.

Q2: What is the maximum RF input power?

The specified maximum input power is 50W. Ensure that the actual operating conditions remain within the rated limit.

Q3: What connectors does this filter use?

The standard model uses SMA-K RF connectors. Please confirm the required connector interface before ordering.

Q4: How does a band pass cavity filter work?

It passes signals within its designated frequency band while attenuating unwanted signals outside that band, helping improve frequency selectivity in an RF system.

Q5: Can the frequency range or attenuation requirements be customized?

Custom configurations may be available. Contact us with your target frequency range, bandwidth, rejection requirements, power level, and connector preferences.

Q6: Is this filter suitable for my RF system?

Compatibility depends on the system's frequency plan, impedance, power level, connector interface, and required attenuation. Please verify these parameters before purchase.
