MMIC technology offering state-of-the-art reliability,
temperature stability, and ruggedness. Selectable bias
modes that optimize efficiency for different output power
levels, and a shutdown mode with low leakage current,
increase handset talk and standby time. The self-
contained 4 mm x 4 mm x 1.1 mm surface mount
package incorporates matching networks optimized
for output power, efficiency, and linearity in a 50
