Our products include attenuators, planar chip inductors, heat spreaders, transmission lines, capacitors, laser diode sub-mounts, lange couplers, microwave filters and chip resistors. Our lange couplers are widely used as power combiners and splitters in microwave amplifiers, mixers & modulators. Our microwave filters are designed to eliminate false signals or harmonics by passing the desired signal or band of signals and rejecting any other signals. Our band-pass filter is a device that passes frequencies within a certain range and rejects all frequencies outside of that range.
