Suited for satellite TV, the MAX2112 zero-IF direct-conversion tuner receives QPSK and 8PSK signals in the 925 to 2,175-MHz range, and downconverts them to baseband for demodulation. It provides an 8.0-dB noise figure and wide 75 to 0-dBm dynamic range, thus eliminating the need for an external LNA.

Housed in a 28-pin TQFN, the MAX2112 operates from a single 3.3-V supply, consumes only 300 mW, and is designed for use with a 27-MHz crystal.
