2300-2390MHz 70W Band-Pass Cavity Filter

Optimized for mid-band wireless infrastructure, the 2300-2390MHz Cavity Filter delivers high-performance signal conditioning for LTE, 4G, and 5G networks. This filter utilize a high-Q cavity structure to achieve a steep 60dB rejection, effectively eliminating adjacent channel interference and noise. With a maximum insertion loss of 1.0dB at center frequency and a return loss of ≥18dB, it maintains exceptional signal stability and power efficiency. Housed in a robust enclosure with N-Female connectors, this 50Ω filter is a cost-effective, reliable choice for professional RF signal processing and network optimization.

What are the primary application scenarios for this 2.3GHz cavity filter?

This filter is specifically designed for Telecommunication Base Stations and Distributed Antenna Systems (DAS). it is used for band separation, interference control in LTE/4G/5G networks, and improving overall signal quality in professional wireless communication infrastructure.

How does the 60dB rejection benefit carrier-grade networks?

A ≥60dB attenuation ensures that unwanted signals outside the 2300-2390MHz band are suppressed by a factor of one million. This high level of isolation is critical for preventing interference from nearby transmitters and maintaining a clean noise floor for high-speed data transmission.

Is the 70W power handling sufficient for base station use?

Yes, the 70W power rating is ideal for mid-power base stations, remote radio heads, and the distribution layers of a DAS. It provides a reliable overhead for continuous high-capacity cellular traffic.

What makes a cavity filter better than other filter types for this band?

Cavity filters offer a much higher “Quality Factor” (Q) compared to microstrip or ceramic filters. This results in lower insertion loss and much steeper rejection curves, which are essential for maintaining signal purity in congested telecommunication bands.

What connector type and impedance are used?

The filter is equipped with standard N-Female connectors and features a 50Ω impedance, ensuring seamless integration with existing professional-grade RF cables and antenna systems.
