摘要： A RF resonator for sensing a physical or an environmental parameter includes a substrate having a substrate surface. A polymer-derived ceramic (PDC) element is positioned on or within the substrate surface. The RF resonator has a resonant frequency that changes as a function of the physical or environmental parameter. A system for wirelessly sensing at least one physical or environmental parameter includes at least one RF resonator and a wireless RF reader located remotely from the RF resonator for transmitting a wide-band RF interrogation signal that excites the RF resonator. The wireless RF reader detects a sensing signal retransmitted by the RF resonator and includes a processor for determining the physical or environmental parameter at the location of the RF resonator from the sensing signal.

摘要： An integrated cavity filter/antenna system includes a substrate, a cavity filter formed in or on the substrate. A first cavity resonator is in or on the substrate that is enclosed by metal walls. At least a second cavity resonator is formed in or on the substrate that is enclosed by metal walls. An inter-resonator coupling structure couples energy between the first cavity resonator and the second cavity resonator. An antenna is integrated with one of the cavity resonators so that the antenna acts as both a port of the cavity filter and as a radiating element for the filter/antenna system. A connector is coupled to one of the cavity resonators for coupling energy into the filter/antenna system.

摘要： A power amplifier is provided, which includes a power dividing unit, a first power amplification tributary, a second power amplification tributary, and an impedance conversion unit. Input ends of the first power amplification tributary and the second power amplification tributary are coupled to two output ends of the power dividing unit respectively. An output end of the first power amplification tributary is coupled to an output end of the second power amplification tributary through the impedance conversion unit. Rated power of a peak power amplifier in the second power amplification tributary is greater than that of a main power amplifier in the first power amplification tributary. The beneficial effects of the present invention lie in that larger back-off exists at the peak of an efficiency curve of the power amplifier, and in the case that power is back-off, efficiency of the power amplifier is improved.
