QFN quad flat-pack no-lead A type of package for surface mount. Because it has no leads it is nearly impossible to hand solder. "Quad" refers to the geometry where connections are made on all four sides of the package; a "DFN" (dual) has leads only on two opposite sides.
QPSK quadrature phase shift keying Also called 4-QAM, this is a method of modulating 2 bits of data at a time to indicate one of four possible states (or symbols), thus doubling the amount of data that can be transmitted over a given bandwidth.
