SLD-3091FZ Datasheet, PDF (1/8 Pages) SIRENZA MICRODEVICES – 30 Watt Discrete LDMOS FET in Ceramic Flanged Package

Product Description
Sirenza Microdevices’ SLD-3091FZ is a robust 30 Watt high performance
LDMOS transistor designed for operation from 10 to 2200MHz. It is an
excellent solution for applications requiring high linearity and efficiency at a
low cost. The SLD-3091FZ is typically used in power amplifiers, repeaters,
and radio amplifier applications. The power transistor is fabricated using
Sirenza’s high performance XeMOS II^TM process.
