Title:
TUNABLE MULTIPLEXER
Document Type and Number:
Japanese Patent JP2006109512
Kind Code:
A
Abstract:

To provide a tunable ferroelectric multiplexer for use in CDMA communications devices.

Tunable ferroelectric capacitors are used to tune the resonance frequencies of several resonators used in a multiplexer and to tune the frequency response shape of the multiplexer. A low-loss ferroelectric material and its configuration are provided. The tunable multiplexer is smaller and has less insertion loss than that of a multiplexer subjected to fixed tuning.
