Ku ADAPTATION FOR PHASE-LOCKED LOOP WITH TWO-POINT MODULATION

摘要

A wireless device includes: an antenna; and a polar-modulation transmitter coupled to the antenna and configured for two-point modulation, the transmitter including: a data input; a first signal path including a multiplier coupled to the data input and a voltage-controlled oscillator gain adaptation module coupled to the multiplier and configured to provide a gain value to the multiplier; and a second signal path coupled to the data input and including an analog phase-locked loop (PLL) including a voltage-controlled oscillator (VCO) coupled to the first signal path.
