LT5518 Overview
Key Features
- It allows direct modulation of an RF signal using differential baseband I and Q signals
- It supports PHS, GSM, EDGE, TD-SCDMA, CDMA, CDMA2000, W-CDMA and other systems
- It may also be configured as an image reject up-converting mixer, by applying 90° phase-shifted signals to the I and Q inputs
- The high impedance I/Q baseband inputs consist of voltage-to-current converters that in turn drive double-balanced mixers
- The balanced I and Q baseband input ports are intended for DC coupling from a source with a common mode voltage level of about 2.1V
- The LO path consists of an LO buffer with single-ended input, and precision quadrature generators that produce the LO drive for the mixers
- The supply voltage range is 4.5V to 5.25V
