Micro-Fabricated DC Comparison Calorimeter for RF Power Measurement
Diode detection and bolometric detection have been widely used to measure radio frequency (RF) power. However, flow calorimeters, in particular micro-fabricated flow calorimeters, have been mostly unexplored as power meters. This paper presents the design, micro-fabrication and characterization of a flow calorimeter. This novel device is capable of measuring power from 100 μW to 200 mW. It has ...
متن کاملAN749: Broadband Transformers and Power Combining Techniques for RF
The input and output transformers are among the most critical components in the design of a multi-octave amplifier. The total performance of the amplifier (linearity, efficiency, VSWR, gain flatness) will depend on their quality. Transformers with high impedance ratios and for low impedances are more difficult to design in general. In the transmission line transformers very low line impedances ...
متن کاملAn Introduction to Broadband Impedance Transformation for RF Power Amplifiers
Introduction When analytically defining radio frequency circuits, a common approach incorporates admittance or impedance. Admittance, which is symbolized by Y, is defined in terms of conductance G and an imaginary susceptance component, jB. Admittance is often useful when defining parallel elements in a network and is expressed by the complex algebraic equation Y = G + jB. Impedance, the mathem...
متن کاملA Suitable Coding Scheme for Broadband Power-line Communication
This paper introduces three coding strategies for using the Luby Transform (LT) code in a relay aided power-line communication scheme. In the first method, the relay decodes the received packets and re-encodes them for transmission towards the destination. In the second method, the relay only forwardes a random linear combination of its received packets towards the destination, while in the thi...
