Abstract: A method and apparatus for providing an oscillating signal within a transmitter/receiver circuit is described. The transmitter/receiver circuit may include an oscillator that generates an oscillating signal that may be provided to a low power, low gain mixer of the transmitter/receiver circuit along a shorter circuit path that includes low power circuitry, such as low power buffers and low power frequency dividers. The oscillating signal may also be provided to a high power, high gain mixer along a longer circuit path that includes high power circuitry, such as high power buffers and high power frequency dividers. Specifically, the low power circuitry is adapted to consume less power in an ON state than the high power circuitry in an ON state, and the shorter circuit path has a shorter electrical path length than the longer circuit path.

Abstract: Techniques for using a narrow filter located before a power amplifier to reduce interference in an adjacent frequency band are disclosed. In an exemplary design, an apparatus (e.g., a wireless device) includes the narrow filter and the power amplifier. The narrow filter is for a first frequency band (e.g., Band 40) and has a first bandwidth that is more narrow than the first frequency band. The narrow filter receives and filters an input radio frequency (RF) signal and provides a filtered RF signal. The power amplifier receives and amplifies the filtered RF signal and provides an amplified RF signal. The apparatus may further include a full filter for the first frequency band and located after the power amplifier. The full filter receives and filters the amplified RF signal and provides an output RF signal when it is selected for use.

Abstract: A biasing device includes closed-loop transconductance slaving circuit, able to slave the time average of the base/emitter or gate/source voltage of the amplifier transistor (Q1) to a reference voltage corresponding to a desired quiescent current for the transistor. Moreover, viewed from the base or gate of the amplifier transistor (Q1), the impedance of the base/emitter or gate/source circuit is small at low frequency, and large with respect to the impedance of the radio frequency source within the radio frequency range of the signal. The device can be incorporated in a mobile terminal, such as a cellular mobile phone.
