28.0 GHz Surface Mount Bandpass Filter
DESCRIPTION
One of DLI’s surface mountable catalog bandpass filters designed for the 5G band. This filter utilizes DLI’s low loss temperature stable materials which offer small size and minimal performance variation over temperature. The catalog BPF’s are offered in a variety of frequency bands, which offers a drop in solution with highly repeatable performance.
