Theoretical and Experimental Analysis of Resonant Microwave Reflection Amplifiers

In this article, the one-port transistor amplifier (OPTA) is studied in detail. This kind of amplifier offers a higher gain, with higher power efficiency at microwave frequencies, than a conventional two-port transmission amplifier. A new theoretical a...
Electromagnetic signals are used to transmit information in the form of amplitude, frequency, phase and time duration of an oscillation. In many cases, they must be amplified from a low to a higher power level by an amplifier having special basic characteristics, such as sufficient gain within a specific...

Theory and Practical Considerations for Measuring Phase Noise Better Than –165 dBc/Hz: Part I

Phase noise requirements have a major influence on the design of a communication system because they impact the local oscillator design and hence the cost of the radio. Since the number of wireless subscribers and thus, RF interference, continues to in...
Phase noise is a frequency domain measure of the short-term stability of an oscillator. It is measured and specified as noise power, relative to carrier power, in a one Hz bandwidth at a given frequency offset. Typically, for a communication system oscillator, the phase noise requirement is specified for...
