  • Patent number: 9768727
    Abstract: An adjustable mixer is disclosed that is capable of operating in different modes in order to satisfy the mixing requirement of multiple radio access technologies (RATs). The adjustable mixer includes a LO signal generating portion and a mixing portion. Depending on the mixing requirements of the RAT, the adjustable mixer can operate in any one of multiple modes, each mode having a specific configuration for the LO signal generating portion and the mixing portion. The LO signal generating portion generates a LO signal having a particular duty cycle, depending on the selected mode, for use by the mixing portion. The mixing portion has an adjustable circuit configuration that can be dynamically reconfigured based on the selected mode, and which allows the mixing portion to successfully mix received signals using the corresponding LO signals generated by the LO signal generating portion.

  • Patent number: 8543073
    Abstract: Methods and systems for loop-through for multi-band TV tuners and set-top box and/or TV set applications are disclosed and may include generating master and slave output signals from one or more low-noise amplifiers including master and slave stages. The master and slave stages may include parallel-coupled gain paths. Gate terminals and source terminals of input transistors for the master and slave stages may be directly coupled. The input transistors for the master and slave stages may share an inductor coupled to the source terminals and to ground. The master and slave stages may include cascode stages. VHF and UHF signals may be amplified in the multi-band receiver. The generated master output signal may be processed in the multi-band receiver, and may be utilized to generate I and Q output signals. A plurality of the slave output signals may be summed and communicated to a receiver external to the multi-band receiver.
