The skin-effect resistance in Schottky-barrier diodes with a complex form of the boundaries is calculated using the theory of R functions and the Ritz variational method. The minimum resistance due to the skin effect is determined by the choice of the diode geometry.

RF image frequency, reducing a mixer’s RF image response can be important because noise at that frequency, including that pro-duced by circuitry between the mixer and antenna, will still be mixed to the desired IF, degrading the signal-to-noise ratio.

This is typically measured at up to volts on the gate (higher potentials will conduct tons of current across the gate Schottky contact which tends to roast your FET) and perhaps or 2 Volts drain-to-source.

This circuit uses the small non-linear response area of a single diode to create combinations of sum and difference frequencies of two input signals (or one input signal containing multiple overtones). A diode is a two-terminal electronic component that conducts current primarily in one direction (asymmetric conductance); it has low (ideally zero) resistance in one direction, and high (ideally infinite) resistance in the other.
A diode vacuum tube or thermionic diode is a vacuum tube with two electrodes, a heated cathode and a plate, in which electrons can flow in only one direction, from. Thus, there must be enough voltage drive to turn the diodes on to allow for the nonlinear intermixing of multiple tones.
When the diode barrier is increased, the mixer will require a higher applied voltage to allow for nonlinear intermixing—hence intermodulation distortion products will be better suppressed.An RF chain is a cascade of electronic components and sub-units which may include amplifiers, filters, mixers, attenuators and detectors.
It can take many forms, for example, as a wide-band receiver-detector for electronic warfare (EW) applications, as a tunable narrow-band receiver for communications purposes, as a repeater in signal distribution systems, or as an amplifier and up-converters.Monolithic dual-quadrature mixer using GaAs FETs.
