power down mode turns off the driver amplifier. The

device features balanced IF inputs, single-ended LO

input and RF output for ease of interface. Packaged in an

industry standard 4mmx4mm, 16-pin, leadless chip car-

rier, the device provides a low-cost solution while easing

board space limitations.
