RF Spiral Filter

We can develop new spiral filter based o customers’requirements

Application

image004.pngSpiral filter easy to realize more complex filter circuit to obtain high selectivity.These characteristics especially within 100-800 mhz

image004.pngIn the circuit and high frequency electronic system has better frequency selective filtering effect,spiral filter can suppress useless out of band signals and noise.In the aviation, aerospace, radar, communication, electronic countermeasure, radio and television and various applications in electronic test equipment

image004.pngMeet various demands of network systems with the Ultra-wideband design.
