专利名称：SWITCHED RF OUTPUT TARGET-TRACK TRANSMITTER 发明人：ALAN ROGER KEITH FARRER 申请号：AU5363686 申请日：19860217 公开号：AU5363686A 公开日：19860821 专利内容由知识产权出版社提供 摘要：A target tracking transmitter has an internal voltage supply which may be operated at a first operative level...
A radiofrequency identification (RFID) multiplexer, which may be in a network, interprets an RF signal from an RFED reader as RFE) tag interrogation data. A single cable directs an
Transmitter circuit for RF communication device, RF communication device, and method of generating an antenna output signal in a transmitter circuit A first switched-capacitor digital-to-analog converter (DAC) receives the first digital output signal and generates a first analog antenna output signal....
Efficiency of an RF/microwave power amplifier is increased at a back-off power level by increasing the load resistance of the amplifier at the reduced output power level as compared to load impedance
RF-CMOSOscillatorswithswitchedTuning Fully integrated CMOS oscillators are of great interest for use in single-chip wireless transceivers.In most oscillator circuits reported to date that operate in the 0.9 to 2 GHz frequency range, an integrated spiral inductor sets the frequency . It is ...
CIRCUITS FOR SWITCHED CAPACITOR RECEIVER FRONT-ENDS Switched capacitor radio frequency receiver front-ends are provided, comprising: a plurality of banks, each comprising: a first switch connected to a RF input signal; a sampling capacitor connected to the first switch and to ground; a se... Y...
This paper presents miniature RF MEMS switched capacitors with pull-down and pull-up electrodes for increased capacitance ratio and power handling. A 2×2 switch array has three operation states: up-state, down-state and up-up state (switch attached to the pull-up electrode), with capacitance...
