US Classification:

4551143, 4551151, 4551142

Abstract:

In accordance with another representative embodiment, a high-frequency signal transmitter a power amplifier configured to supply a high-frequency signal; an antenna configured to transmit the high-frequency signal; a transmission line configured to transfer the high-frequency signal from the power amplifier to the antenna; and an impedance matching circuit connected to the transmission line. The high-frequency signal transmitter also comprises a mismatch detector. The mismatch detector is configured to designate a comparatively poor linearity region and a comparatively good linearity region by dividing a Smith chart into the two regions based on Adjacent Channel Power Ratio (ACPR) contours drawn on the Smith chart at a point on the transmission line where the impedance matching circuit is connected, to measure a time-dependent reflection coefficient of the high-frequency signal transmitter in terms of a phase and a magnitude, to determine whether the reflection coefficient is located in the comparatively poor linearity region or the comparatively good linearity region, and based on a result of the determination, to improve the linearity of the high-frequency signal transmitter.

US Classification:

333124, 333 32

Abstract:

In accordance with a representative embodiment, an impedance matching circuit for use at an output stage of a power amplifier is disclosed. The impedance matching circuit comprises: an input port for receiving a frequency band signal; and a plurality of paths, each path being allocated with a principal band signal to be transmitted therethrough and including a path on-off network and a fixed-value impedance matching network. Depending on a type of the received frequency band signal, the path on-off network is configured to activate a selected one of the plurality of paths by rendering an input impedance of the selected path to have a lower absolute magnitude so that the signal is transmitted therethrough, and to deactivate the remaining paths of the plurality of paths by rendering the input impedance thereof to have a higher absolute magnitude so that the signal is not transmitted therethrough. The fixed-value impedance matching network matches a load impedance of the output port of each path to the input impedance thereof, thereby rendering the input impedance thereof to have a prescribed reference value with respect to the principal band signal when said path is activated by the path on-off network.
