Abstract: Methods and systems for a configurable low-noise amplifier with programmable band-selection filters may comprise a low-noise amplifier (LNA) with a low pass filter coupled to a first input of the LNA and a high pass filter coupled to a second input of the LNA. The low pass filter and the high pass filter may also be coupled to a signal source input. Signals may be received in a pass band of the high pass filter and a pass band of the low pass filter. Input signals in the pass band of the one filter (but not signals in the pass band of the other filter) may be amplified by coupling the one input of the LNA to ground and coupling the other filter to ground utilizing a shunt resistor. The filters may be configurable and may each comprise at least one inductor and at least one capacitor.

Abstract: A system comprises a microwave backhaul outdoor unit having a first resonant circuit, phase error determination circuitry, and phase error compensation circuitry. The first resonant circuit is operable to generate a first signal characterized by a first amount of phase noise and a first amount of temperature stability. The phase error determination circuitry is operable to generate a phase error signal indicative of phase error between the first signal and a second signal, wherein the second signal is characterized by a second amount of phase noise that is greater than the first amount of phase noise, and the second signal is characterized by a second amount of temperature instability that is less than the first amount of temperature instability. The phase error compensation circuitry is operable to adjust the phase of a data signal based on the phase error signal, the adjustment resulting in a phase compensated signal.

Abstract: Methods and systems for a sampled loop filter in a phase locked loop (PLL) may comprise a phase locked loop (PLL) comprising a phase frequency detector, a sampled loop filter comprising a plurality of capacitors and at least one switch, a plurality of voltage controlled oscillators (VCOs) coupled to said sampled loop filter, and a frequency divider. The PLL generates at least one clock signal, and the sampled loop filter samples an output signal from the phase frequency detector when an average of charge provided to a first of the plurality of capacitors in the sampled loop filter is zero. The frequency divider may be a fractional-N divider. A second switch in said sampled loop filter may have switching times that are non-overlapping with switching times of the at least one switch. Capacitors may be coupled to ground from each terminal of the second switch.

Abstract: Aspects of methods and systems for high frequency signal selection are provided. The system for high frequency signal selection comprises a first driver and a second driver. The first driver is able to receive a first high frequency input, and the second driver is able to receive a second high frequency input. The output of the first driver is operably coupled, via a first inductive element, to a first resistive load and a first buffer, and the second driver is operably coupled, via a second inductive element, to the output of the first driver. One or both of the first high frequency input and the second high frequency input may be transferred to the first buffer by selectively enabling a current to one or both of the first driver and the second driver, respectively.
