摘要： There is provided wireless transmitter that includes a poly phase filter (PPF) configured to receive an input differential intermediate frequency (IF) signal and to generate an in-phase differential IF signal and a quadrature differential IF signal. The wireless transmitter further includes a transformer-based circuit configured to receive an input differential local oscillator (LO) signal and to generate an in-phase differential LO signal and a quadrature differential LO signal based on the input differential LO signal. In addition, the wireless transmitter includes a mixer configured to multiplicatively mix the in-phase differential IF signal with the quadrature differential LO signal to produce a first RF signal component and to multiplicatively mix the quadrature differential IF signal with the in-phase differential LO signal to produce a second RF signal component, the mixer further configured to provide a differential RF signal comprising a (filtered or unfiltered) combination of the first RF signal component and the second RF signal component. Furthermore, the wireless transmitter includes an amplification stage configured to amplify the differential RF signal, the amplification stage comprising a driver stage and a power amplifier stage.

摘要： According to one embodiment, an RF frontend IC device includes a first array of transceivers to transmit and receive RF signals of a first polarization associated with a first set of RF channels. The device includes a second array of transceivers to transmit and receive RF signals of a second polarization associated with a second set of RF channels. The device includes a first converter coupled to each transceiver of the first array of transceivers and a second converter coupled to each transceiver of the second array of transceivers. The first converter is to up-convert or down-convert a signal of the first polarization based on a LO signal. The second converter is to up-convert or down-convert a signal of the second polarization based on the LO signal. The first and second array of transceivers, and the first and second converters may be implemented within a single IC chip.

摘要： An RF frontend integrated circuit (IC) device comprises one or more RF transceivers to transmit and receive RF signals within a first frequency band and a second frequency band that is higher than the first frequency band. The RF frontend IC device further comprises a bidirectional LO signal generation circuit coupled to the one or more transceivers to generate a bidirectional LO signal. The bidirectional LO signal is injected between the first frequency band and the second frequency band. The bidirectional LO signal generation circuit is to perform a high-side LO injection for the RF signals within the first frequency band by injecting the bidirectional LO signal having an LO frequency higher than the first frequency band and to perform a low-side LO injection for the RF signals within the second frequency band by injecting the bidirectional LO signal having the LO frequency lower than the second frequency band.

摘要： According to one embodiment, an RF frontend IC device includes a first RF transceiver to transmit and receive RF signals within a first frequency band and a second RF transceiver to transmit and receive RF signals within a second frequency band that is different than the first frequency band. The RF frontend IC device further includes a converter and a multi-band local oscillator (LO) generator to provide LO signals to the converter. The multi-band LO generator includes a phase-lock loop (PLL) circuit operating at a PLL operating frequency, wherein the PLL operating frequency is outside of the first frequency band and the second frequency band. The multi-band LO generator also includes multiple frequency multipliers coupled to the PLL circuit to upscale the PLL operating frequency and to generate an LO signal having a frequency within a predetermined proximity from the frequency band.
