Sirenza Microdevices’ XD010-51S-D4F 15W power module is a robust 2-

stage Class A/AB amplifier module is a driver stage in many 900 MHz

applications. The power transistors are fabricated using Sirenza's latest,

high performance LDMOS process. This unit operates from a single volt-

age

supply and has internal temperature compensation of the bias volt-

age to ensure stable performance over the full temperature range. It is a

drop-in, no-tune solution for medium power applications requiring high effi-

ciency, excellent linearity, and unit-to-unit repeatability. It is internally

matched to 50 ohms.
