It allows direct modulation of an RF signal using differential baseband I and Q signals. It supports LTE, GSM, EDGE, TD-SCDMA, CDMA, CDMA2000, W-CDMA, Wi Max and other munication standards. It can also be configured as an image reject upconverting mixer, by applying 90° phase-shifted signals to the I and Q inputs. The I/Q baseband inputs drive double-balanced mixers. An onchip balun converts the differential mixer signals to a 50Ω single-ended RF output. Four balanced I and Q baseband input ports are DC-coupled with a mon mode voltage level of 0.5V. The LO path consists of an LO buffer with single-ended or differential inputs and precision quadrature generators to drive the mixers. The supply voltage range is 3.15V to 3.45V. An external voltage can be applied to the LINOPT pin to further improve 3rd‑order linearity performance.
