Low Noise UHF Convertor using Backward Diode

Low-noise, tunable diode laser for ultra-high-resolution spectroscopy.

We demonstrate the excellent spectral properties of a diode laser setup that combines good tunability with superb short-term frequency stability and controllability. It is based on merging two concepts, the diode laser with resonant optical feedback and the grating stabilized diode laser. To characterize the short-term performance we beat two essentially identical diode lasers and find a short-...

A W-band Simultaneously Matched Power and Noise Low Noise Amplifier Using CMOS 0.13µm

A complete procedure for the design of W-band low noise amplifier in MMIC technology is presented. The design is based on a simultaneously power and noise matched technique. For implementing the method, scalable bilateral transistor model parameters should be first extracted. The model is also used for transmission line utilized in the amplifier circuit. In the presented method, input/output ma...

Simple Low Cost UHF RFID Reader

We describe a UHF RFID reader which uses low cost off-the-shelf components such as MSP430 microcontroller and the TH7203x transmitter IC. The receiver circuit is based on envelope detector and analog data slicer. The design is very simple and can be used as an educational tool for academic

A Novel Low-profile Wideband Uhf Antenna

Abstract—In this paper, an ultra high frequency (UHF) low-profile antenna is proposed; it is based on the discone antenna but with addition of a back cavity, a short-circuiting structure and a two-plate top structure in order to achieve both low-profile and wideband. It is simulated and prototyped. The test results show that the antenna has an omni-directional radiation pattern in the horizonta...
