4 [OMEGA] quarter-wave transmission line is an impedance transformer for impedance matching between the amplifier and the external system.
At microwave frequencies, all these lumped parallel circuits connected in series should be replaced by a quarter-wave transmission line short-circuited at the output.
In class F, to approximate a 100 percent collector efficiency, one or several parallel circuits tuned at the harmonic components or a quarter-wave transmission line are used as the parallel circuit single-frequency equivalent.
A quarter-wave transmission line is used to supply the reverse voltage.
If this impedance is normalized to the system impedance of 50 [omega] plotted on a Smith Chart and rotated the length of the quarter-wave transmission line, 90[degrees], the resulting normalized impedance is 0.
The quarter-wave transmission line required to set the operating frequency consists of a portion of the MMIC, the bond wire length, the lead frame and the coplanar waveguide (CPW) line on the printed circuit board.
In general, to obtain a desired input impedance, a quarter-wave transmission line is used, or the antenna is fed in a nonradiating edge point having the desired input impedance.
