LTC5588IPF-1#PBF

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 on-chip balun converts the differential mixer signals to a 50 ohm 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. It is used in applications such as image reject upconverters, point-to-point microwave links, broadcast modulator, military radio etc.
