Transfer ratio in complex form

Lecture



Based on the obtained equivalent circuit, for the voltage at the output of the circuit can be written:

  Transfer ratio in complex form

Then the transfer coefficient of the input device:

  Transfer ratio in complex form

Where   Transfer ratio in complex form - the conductivity of the load is equal to the sum of the conductivity of the circuit and the recalculated conductivity of the input of the first cascade;

         Transfer ratio in complex form - the resulting conductivity of the circuit, taking into account the conductivities introduced by the antenna-feeder system and the input of the first cascade.

From the resulting expression for   Transfer ratio in complex form it follows that the transfer coefficient depends on the inclusion (transformation) coefficients at the input m 1 and output m 2 of the electoral system, as well as the relationship of conductances   Transfer ratio in complex form antennas as signal source and resulting conductance   Transfer ratio in complex form input device.

Included in the expression for   Transfer ratio in complex form magnitude   Transfer ratio in complex form varies with frequency within each sub-band relatively slowly. Resulting conductivity   Transfer ratio in complex form has a pronounced minimum at the resonant frequency of the parallel circuit. Assuming that   Transfer ratio in complex form and   Transfer ratio in complex form real numbers, independent of frequency, the transfer coefficient   Transfer ratio in complex form has a maximum that almost coincides with the natural frequency of the input circuit with the resulting parameters. We define the module angle of phase shift of the transmission coefficient. For this expression for   Transfer ratio in complex form we will present in the following form:
