Our products

Cavity Filter

Cavity filters are high-performance RF and microwave filters designed for applications requiring low insertion loss, high selectivity, and excellent power handling.

Ceramic Filter

High-Q filters with excellent thermal stability and low insertion loss. Ceramic resonators make them ideal for wireless systems, communications and rugged environments.

Crystal Filter

Ultra-narrowband filters with outstanding frequency precision and long-term stability. Often used in IF stages and mission-critical RF signal paths.

Custom Magnetics

Designs and manufactures custom and standard coils, solenoids, and inductive products for RF, power, and industrial applications worldwide.

LC/Microwave Filter

Reliable, custom-built filters using lumped-element (LC) or distributed microwave topologies. Ideal for EMI suppression, signal conditioning and frequency selection across a wide range of bands.

Monolithic Filter

Monolithic construction ensures tight tolerance and excellent thermal stability across production runs.

Oscillator

Frequency control modules designed for low phase noise and excellent temperature stability. Available in multiple package types and configurations.

Quartz Crystal

For crystal-based stable signal applications, we offer SMD and through-hole packages, meeting requirements from consumer standards up to military and space specifications.

Saw Filter

Surface Acoustic Wave filters with excellent frequency stability and sharp selectivity. Perfect for compact devices that require consistent performance in harsh conditions.
