1 GHz to 2 GHz – Bandpass Filter

Service Description

End Product + Design Documents + Production Documents

This band pass filter features an eleven-section combline design, optimized for applications such as satellite communications. It provides a 2 GHz wide passband, covering the frequency range from 2 GHz to 4 GHz.

Engineered for strong out-of-band suppression, the filter achieves 55 dB rejection at both 1.3 GHz and 6 GHz — corresponding to ±3 GHz from the center frequency. Despite its high selectivity, it maintains a low maximum insertion loss of just 2 dB across the passband.

The filter is equipped with SMA female connectors, making it compatible with standard 50 Ohm RF systems. Its robust electrical performance and wide bandwidth make it a solid choice for demanding communication environments.
