ruggedness. There are three 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 mm surface mount
package incorporates matching networks optimized for
output power, efficiency, and linearity in a 50 Ω system.
