Impedance Matching,is the design of a circuit to be inserted between a source and a load (both used in the general sense) so as to provide maximum power transfer between them. For example, the source could be a 50-ohm r.f. signal generator and the load could be the optimal input impedance of a transistor under certain

Power Amplifiers,model for the purposes of analysis and design. For power transistors, however, linear models are not applicable in describing the terminal behaviour of the transistors. The behaviour simply varies with the power level.

Oscillators,- and .-parameters, or based on large-signal behaviour of the transistors. The former category is sometimes known as the linear oscillator whereas the latter is sometimes referred to as the power or large-signal oscillator.

Microwave Frequency Counting,ounting the number of pulses within a specified duration of time. The counted data is then converted into a frequency reading to be displayed digitally. Being a digital instrument, the frequency range that a frequency counter can measure is limited by the speed of its logic circuitry. A state-of-the

Noise Measurement,eceived in the midst of noise. In any electronic system there are noises generated within and outside the system. In most modern electronic systems the noise generated within the system itself contributes a significant proportion of the total noise, and in most cases, the internally generated noise
