The IC combines an LNA, followed by a double-conversion RF/IF downconverter block and a PLL frequency synthesizer on one chip. The second IF Freqency is a pseudo- baseband signal into a on-chip 2-bit A/D converters.The device can operate on a supply voltage as low as 2.7 V, and is a housed in a small 36 pin QFN (Quad, Flat, No-lead) package, resulting in a very low power consumption and reduced board space. NEC's stringent quality assurance and test procedures ensure the highest reliability and performance.
