It receives all television bands from 47MHz to 862MHz and converts the selected channel to an industry-standard 36MHz IF. The MAX3544 includes a variable-gain low-noise input amplifier; an RF tracking filter; an image rejection mixer; a peak detector; an optional internal, self-contained RF gain-control loop (RFAGC); a VCO with fractional-N PLL; an IF bandpass filter; an IF variable-gain amplifier; and a crystal oscillator. The MAX3544 is available in a small, 6mm x 6mm, thin QFN package, and the application circuit fits in 20mm x 25mm on a two-layer board with single-sided ponent mounting.
