LT5522EUF#PBF

LT5522 is an active down converting mixer. It is optimized for high linearity downconverter applications including cable and wireless infrastructure. The IC includes a high speed differential LO buffer amplifier driving a double-balanced mixer. The LO buffer is internally matched for wideband, single-ended operation with no external components. The RF input port incorporates an integrated RF transformer and is internally matched over the 1.2GHz to 2.3GHz frequency range with no external components. The RF input match can be shifted down to 400MHz, or upto 2.7GHz, with a single shunt capacitor or inductor, respectively. The high level of integration minimizes the total solution cost, board space and system-level variation. It is used in applications such as cellular, PCS and UMTS band infrastructure, CATV downlink infrastructure, 2.4GHz ISM, high linearity down mixer applications.
