Dielectric Bandpass Filters (BP-S) Introduction

Token Dielectric Bandpass Filters (BP-S) for high performance microwave filters and oscillators

< >
  • High Frequency Selectivity Filters (BP-S)

(BP-S) series with a high dielectric constant, is the best microwave filters and oscillators.

Token Ceramic Dielectric material has a high dielectric constant and high Q values, and high temperature stability, especially for the design and stability of the microwave oscillations and filtering. German bond ceramic media for CT1, CT2, 900MHz, 1.8GHz, 2.4GHz, 5.8GHz cordless phones, wireless headsets, wireless microphones.

Token electronics manufacturing microwave dielectric filters, multi-layer filters, cavity filters, band-pass filter, military filters, and high-frequency filters, using low insertion loss, high Q, high frequency selectivity, and microwave dielectric ceramics to meet specific design requirements. Comply with RoHS standards.

(BP-S) series of dielectric filters and stable temperature coefficient, small size and high stability, low insertion loss and good weldability. Dielectric band-pass filter for use in microwave communications, data transmission, radar, electronic warfare, military, aerospace and other fields.

Custom parts are available on request. Token will also produce devices outside these specifications to meet specific customer requirements, please contact our sales for more information.
