摘要： A quadrature connected passive mixer arrangement for frequency converting analog signals from a first to a second frequency. The arrangement comprises two parallel connected mixers provided as transistors. First and second LO signals and their inverse signals having separated phases are provided for driving the transistors. Signal path switches are provided between the RF terminals and the mixer transistors. The switches are driven by signals having a different phase than the signal driving the corresponding mixer transistor. Thus, any short circuit between IF terminals of the arrangement may be eliminated.

摘要： A clock generator circuit may generate a target clock signal and may include a pattern generator to generate a pre-distorted version of a modulation signal from patterns stored by the pattern generator. An up-converter may up-convert the pre-distorted version of the modulation signal and a radio frequency lock oscillator signal to obtain an RF clock signal having a desired frequency tone. A tone detection circuit may receive the RF clock signal and detect a presence of unwanted tones. A controller may write the patterns corresponding to the pre-distorted version of the modulation signal to the pattern generator based on the detected unwanted tones in the RF clock signal.

摘要： An RF amplifier can include a differential inductor for single-ended-to-differential signal conversion. With a center tap of the differential inductor coupled to signal ground and the RF input signal coupled to one of the end taps of the inductor, the negative of the RF input signal is obtained at the other end tap of the inductor. The differential RF signal produced can be coupled to a differential transistor amplifier that has cross-coupling capacitances, improving the signal balance of the differential output signal.
