ECHO Microwave's substrate band pass filters are available in both Suspended Substrate Stripline (SSS) and Thin Film configurations, covering frequencies from 1 GHz to 50 GHz. SSS designs utilize precision CNC-milled cavities with suspended dielectric substrates to achieve extremely wide passbands, high Q-values, and low insertion loss — outperforming conventional microstrip filters in broadband applications. Thin Film designs, available from 6 GHz to 40 GHz, offer excellent repeatability and compact SMT packaging using high dielectric constant substrates (Er: 9.8), making them ideal for volume production and board-level integration. Our substrate band pass filters are widely deployed in military radar, aerospace transponders, satellite communication payloads, and electronic warfare receivers where wideband frequency selection with minimal signal degradation is essential. Both connectorized and surface-mount options are available with power handling up to 10W.
