LT5522EUF#PBF

LINEAR TECHNOLOGY  LT5522EUF#PBF  芯片, 下混频器

The is a 400MHz to 2.7GHz high signal level Down-converting Mixer is optimized for high linearity down-converter 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 1.2 to 2.3GHz frequency range with no external components. The RF input match can be shifted down to 400MHz 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.
