Multiband matching circuit for a power amplifier |
摘要 |
An impedance-matching circuit for a multiband power amplifier, which uses an impedance-matching circuit with one-to-multiple path to efficiently transmit a radio frequency (RF) from an input port to the corresponding multi-ports without spurious effect. The impedance-matching circuit includes an input port for receiving a plurality of frequency band signals; a plurality of output ports for outputting the plurality of frequency band signals; and a plurality of frequency paths in which each path has an impedance matching network for matching an input port's impedance with its output port's impedance in a desired band; and a short circuit for filtering out RF signals in other remaining bands.
