characteristic-impedance transmission line (CCITL) system using a bilinear transformation approach," Progress In Electromagnetics Research, Vol.
The input matching circuitry is designed to conjugately
match the phase shifter output impedance to the low gate impedance of the FET at the subharmonic input frequency.
The reactance part of the impedance, as showed in Figure 7(b), follows a positive value with a linear variation with frequency, pertaining to an inductance that conjugately
matches or, equivalently, cancels the effect of the 1.
Utilizing supplied linear S-parameters, the MESFET's input was conjugately
matched at the input frequency via a lowpass matching network, and the output impedance of the FET was matched to the desired x 2 output utilizing a high pass network.
To maximize the tag performance, tag antennas must be appropriately designed to conjugately
match the chip impedance .
