Second harmonic tuning of an active RF device |
摘要 |
Second-order harmonic tuning of an active device, such as a transistor used in a radio frequency (RF) power amplifier circuit, is accomplished by positioning a quarter-wavelength stub along a transmission line coupled to an output of the device, such that the output is presented with a desired impedance for the second harmonic.
