Parametric Amplifier Types: The basic Parametric Amplifier Types have already been discussed in detail, but several others also exist. They differ from one another in the variable reactance used, the…
High Frequency Limitations: As stated, transistors suffer from High Frequency Limitations. These are of a twofold nature. On the one hand, there are the same difficulties as those encountered with…
Surface Acoustic Waves Devices(SAW): Surface Acoustic Waves Devices may be propagated on the surfaces of solid piezoelectric materials, at frequencies in the VHF and UHF regions. Devices employing SAW principles…
Stripline and Microstrip Transmission Line: Stripline and Microstrip Transmission Line are physically related to transmission lines but are covered here because they are microwave circuits used in conjunction with semiconductor…
Traveling Wave Tube Working(TWT): Like the multicavity klystron, the Traveling Wave Tube Working is a linear-beam tube used as a microwave amplifier. Unlike the klystron, however, it is a device…
Cavity Resonators: A cavity resonators is a piece of waveguide closed off at both ends with metallic planes. Where propagation in the longitudinal direction took place in the waveguide, standing…
Impedance Matching and Tuning in Waveguide: We know that suitably chosen series or parallel pieces of transmission line had properties which made them useful for providing resistive or reactive impedances.…
