SLD-1000
Product Description
4 Watt Discrete LDMOS FET -Bare Die
Sirenza Microdevices’ SLD-1000 is a robust 4 Watt high performance
LDMOS transistor die, designed for operation from 10 to 2700MHz. It
is an excellent solution for applications requiring high linearity and effi-
ciency. The SLD-1000 is typically used as a driver or output stage for
power amplifier, or transmitter applications. These robust power tran-
sistors are fabricated using Sirenza’s high performance XEMOS IITM
process.
