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 II
TM
process.

Note 1:
Gate voltage must be applied to to the device
concurrently or after application of drain voltage to
prevent potentially destructive oscillations. Bias voltages should
never be applied to the transistor unless it is properly termi-
nated on both input and output.
Note 2:
The required V
GS
corresponding to a specific I
DQ
will vary from
device to device due to the normal die-to-die variation in thresh-
old voltage with LDMOS transistors.
Note 3:
The threshold voltage (V
GSTH
) of LDMOS transistors varies with
device temperature. External temperature compensation may
be required. See Sirenza application notes AN-067 LDMOS
Bias Temperature
Compensation.
