The design of passive circulators/duplexers for RFID applications in the UHF band is presented. The design idea is based on the use of simple passive directional couplers, offering simplicity and low ...

These base station duplexers use six 4” x 3” cavities. They are ideal for compact high performance applications. They are designed to cover either the VHF or the UHF frequency ...

A class of frequency-agile planar duplexers with independently controllable channels in terms of center frequency, passband-width, out-of-band power-attenuation characteristics, and tune-all ...

The TQQ6103 is a high performance BAW duplexer for Band 3 uplink/downlink. With key features including a 75 MHz bandwidth, high attenuation, low loss, and no required external matching, these filters ...

Editor’s note : I have always been greatly impressed with the high speed development work that imec does. This article first appeared in the imec magazine June 2015 issue and I wanted to share this ...

Researchers at Houston's Rice University have demonstrated how UHF frequencies can be used for so-called "super Wi-Fi" without significantly interfering with legacy TV broadcasts.

Kumu's self-interference cancellation technology will also help with FDD by allowing the creation of “smart” adaptive duplexers that let multiple frequency bands use one duplexer.

Basic Process Flow for FBAR Duplexer. Fabrication Process Flow A basic process flow for making the FBAR duplexers is shown in Figure 1. The first step is to prepare the silicon substrate; the surface ...
