  • Interchangeable receive inputs for band and system swappability in communication systems and related methods
    Patent number: 7333831
    Abstract: Interchangeable high band low-noise-amplifiers (LNAs) and low band low-noise-amplifiers (LNAs) and related methods are disclosed that greatly enhance the efficiency of designing handsets for different combinations of frequency bands. The input signals to particular pins on a receiver or transceiver integrated circuit (IC) are swappable such that multiple frequency bands can be input to the same input pins thereby allowing for simplified system design. Efficient programmable techniques are also disclosed for controlling a swap mode within communication ICs. These interchangeable or band swappable input paths, for example, can be utilized to allow interchangeability between high band (PCS, DCS) and low band (GSM, E-GSM) inputs for cellular communications.

  • Apparatus and method for front-end circuitry in radio-frequency apparatus
    Patent number: 7035611
    Abstract: A radio-frequency (RF) apparatus includes front-end circuitry. The front-end circuitry includes a filter circuitry and an impedance matching circuitry. The filter circuitry has a differential output that has an output impedance. The filter circuitry filters signals outside a signal band of interest. The impedance matching network has a differential input coupled to the output of the filter circuitry. The impedance matching network also has a differential output coupled to a signal processing circuitry. The signal processing circuitry has an input impedance. The impedance matching network matches the input impedance of the signal processing circuitry to the output impedance of the filter circuitry.
