摘要： An embodiment of an amplifier has a bandwidth defined by low and upper cutoff frequencies. The amplifier includes an input impedance matching circuit and a transistor. The transistor has a gate, a first current conducting terminal coupled to an output of the amplifier, and a second current conducting terminal coupled to a reference node. The input impedance matching circuit has a filter input coupled to an input of the amplifier, a filter output coupled to the gate of the transistor, and a multiple pole filter coupled between the filter input and the filter output. A first pole of the filter is positioned at a first frequency within the bandwidth, and a second pole of the filter is positioned at a second frequency outside the bandwidth. The input impedance matching circuit is configured to filter the input RF signal to produce a filtered RF signal at the filter output.

摘要： A device includes multiple ceramic capacitors and a current path structure. A first ceramic capacitor includes a first ceramic material between first and second electrodes. A second ceramic capacitor includes a second ceramic material between third and fourth electrodes. The second ceramic material has a higher Q than the first ceramic material. The current path structure includes a lateral conductor located between the first and second ceramic materials, and first and second vertical conductors that extend from first and second ends of the lateral conductor to a device surface. The device may be coupled to a substrate of a packaged RF amplifier device, which also includes a transistor. For example, the device may form a portion of an output impedance matching circuit coupled between a current carrying terminal of the transistor and an output lead of the RF amplifier device.

摘要： The embodiments described herein can provide improved signal feeding between hybrid couplers and associated transistors. As such, these embodiments can improve the performance of amplifiers and other such RF devices that utilize these components. In one embodiment a device includes a distribution network and a compensation resonator. The distribution network is configured to output a signal through a relatively wide output feedline. This relatively wide output feedline provides distributed signal feeding that can improve signal distribution and performance. The output feedline is coupled to the compensation resonator. In general, the compensation resonator is configured to resonate with the distribution network at the frequency band of the signal. Thus, the distribution network and compensation resonator together can provide improved signal distribution while maintaining performance at the frequencies of interest.
