  • Publication number: 20210320081
    Abstract: Packaged modules for use in wireless devices are disclosed. A substrate supports integrated circuit die including at least a portion of a baseband system and a front end system, an oscillator assembly, and an antenna. The oscillator assembly includes an enclosure to enclose the oscillator and conductive pillars formed at least partially within a side of the enclosure to conduct signals between the top and bottom surfaces of the oscillator assembly. Components can be vertically integrated to save space and reduce trace length. Vertical integration provides an overhang volume that can include discrete components. Radio frequency shielding and ground planes within the substrate shield the front end system and antenna from radio frequency interference. Stacked filter assemblies include passive surface mount devices to filter radio frequency signals.

  • Publication number: 20210218373
    Abstract: Low noise amplifiers (LNAs) with low noise figure are provided. In certain embodiments, an LNA includes a single-ended LNA stage including an input for receiving a single-ended input signal from an antenna and an output for providing a single-ended amplified signal, a balun for converting the single-ended amplified signal to a differential signal, and a variable gain differential amplification stage for amplifying the differential signal from the balun. Implementing the LNA in this manner provides low noise figure, high gain, flexibility in controlling gain, and less sensitivity to ground/supply impedance.

  • Patent number: 10560202
    Abstract: Systems and methods are provided for reducing the effects of an impedance mismatch between a communications system and a shared communications medium. A communication system, such as a transceiver within a cable modem, switches between various operating modes including a transmit mode, a receive mode, and a standby mode. The standby mode may be used while the transceiver is in an idle state between modes, such as while changing an amplifier gain states in between transmissions. While transitioning between modes, the impedance presented by the communications system can temporarily fluctuate causing unwanted signal reflections to propagate out of the communications system and on to the shared medium. Circuitry within the communications system, such as transmission circuitry including an adjustable attenuator, may be placed into a hybrid attenuation-isolation mode during the transition causing the magnitude of any unwanted signal reflections to be attenuated and reducing the impact on the shared medium.
