For a lumped-circuit power amplifier, in order to approximate the ideal class F with harmonic impedance conditions of [Z.sub.1] = [Z.sub.3] = [infinity] and [ohm]o [Z.sub.2] = 0 [ohm]o at the device output terminal by compensating the influence of [C.sub.out], it is also advisable to use an additional parallel circuit [L.sub.2][C.sub.2] connected in parallel, as shown in Figure 4, where the series resonant circuit
[L.sub.0][C.sub.0] is tuned at the fundamental.
The tuning sensitivity depends on the available capacity variation and is inversely proportional to the loaded Q of the resonant circuit
. However, frequency dependency of the tuning sensitivity also must be borne in mind.
On the contrary, if the input impedance after step 1 in the broadband matching process has an inductive component and a capacitive component at the lower and higher band edge frequencies, respectively, then a series resonant circuit
that has its resonant frequency occurring at the center of the operating range connected in series with the aforementioned circuit is necessary.
