The LTC5588-1 is a direct conversion I/Q modulator designed for high performance wireless applications. 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, WiMax and other communication 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 common 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. Accurate temperature dependent calibrations can be performed using the on-chip thermistor.
