Additional Details

The LT5522 active downconverting mixer 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 600MHz, or up to 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.

The LT5522 delivers high performance and small size without excessive power consumption.

*Operation over a wider frequency range is possible with reduced performance. Consult factory for information and assistance.

Applications

Cellular, PCS and UMTS Band Infrastructure
CATV Downlink Infrastructure
2.4GHz ISM
High Linearity Downmixer Applications
