| Application Note: T/R Switch For IMT-2000 Handset Applications |
This article from Skyworks Solutions addresses a handset T/R switch design that enables its antennas to be electronically connected to either the transmitter or receiver. It covers both the 1885 - 1980 MHz transmit band (uplink) and the 2110 - 2170 MHz receive band (downlink). Since the T/R switch is placed at the RF front end of the handset, it has significant influence on transmitter efficiency, receiver sensitivity, and battery consumption. |

| White Paper: Ensuring Successful Operation Of RFID Tags In High Value Asset Tracking |
Radio Frequency Identification (RFID) is not a new technology, with the initial application being IFF (Identification Friend or Foe) used by aircraft during World War II. Since that time it has found a variety of uses including key fobs, contactless payment, proximity cards for building security, and toll collection. These days, thanks to increases in performance and standards, RFID readers and tags are finding new life in applications like defense logistics, healthcare, and enterprise. |
