摘要： A narrow band, tunable antenna uses a series of small inductors wired in series to produce different resonant frequencies from a single antenna across a wide frequency spectrum. Radio Frequency (RF) switches are positioned in parallel with the inductors and are capable of shunting a selected inductor out of the antenna circuit thereby changing the electrical length of the antenna and consequently, the resonant frequency. The RF switch control circuitry is isolated from the RF current in the antenna.

摘要： A receiver includes a low noise amplifier (LNA), a passive mixer, a passive filter, a baseband processing block and a voltage controller. The LNA receives and amplifies a radio frequency (RF) signal. The passive mixer is coupled to the LNA without any AC coupling capacitance therebetween, and generates an intermediate frequency signal by down-converting the RF signal. The passive filter filters the intermediate frequency signal. The baseband processing block includes a transimpedance amplifier (TIA) and processes the filtered intermediate frequency signal. The voltage controller keeps a first node and a second node of a signal path to be around a common DC voltage, wherein the first node is located between an output terminal of the LNA and an input terminal of the passive mixer, and the second node is located between an output terminal of the passive mixer and an output terminal of the TIA.

摘要： A receiver circuit, e.g., a low-IF receiver, including two mixing paths. The two mixing paths scale an input signal respectively by two mixing gains and shift phase of the input signal respectively by two mixing phase offsets to provide two mixed signals. The two mixing gains and the two mixing phase offsets are arranged to produce an amplitude adjustment between amplitudes of the two mixed signals and a phase difference of 90 degrees plus a phase adjustment between phases of the two mixed signals. With the amplitude adjustment and/or the phase adjustment properly tuned to nonzero value(s) in association with band-pass response of the receiver circuit, image rejection can be achieved and optimized. Associated method is also disclosed.

Each second stage mixer is configured to mix the first intermediate signal and a divided local oscillator signal to generate second intermediate frequency signals that each represent a band from the multiband radio frequency signal. The frequency divider is configured to provide a different divided local oscillator signal to each of the second stage mixers.

摘要： A receiver uses a local oscillator to receive data transmitted via a combination of radio frequency signals using carrier aggregation. Each radio frequency signal occupies a respective radio frequency band and the radio frequency bands are arranged in two groups, a first group and a second group, separated in frequency by a first frequency region, each of the groups including one or more radio frequency bands and the first group occupying a wider frequency region than the second group. The radio frequency signals are processed using the local oscillator by setting the local oscillator, during the processing, to a frequency that is offset from the center of a band defined by outer edges of the frequency regions occupied by the two groups.

The RF circuit may include a first mixer circuit that provides a first frequency offset for the impedance image and a second mixer circuit that provides an additional frequency offset. Accordingly, the second mixer circuit may allow for adjustments to a total frequency offset of the impedance image. The second mixer circuit may also be configured so that the impedance image rejects a negative frequency impedance response of the reactive circuit impedance response.
