MRFG35003NT1(MT1) BWA 2.4-2.5 GHz REFERENCE DESIGN
Designed by: Monte Miller and Rick Hooper
This reference design is designed to demonstrate the typi-
cal RF performance characteristics of the
MRFG35003NT1(MT1) when applied for the 2.4-2.5 GHz
W-CDMA frequency band. The reference design is tuned for
the best tradeoff between good W-CDMA linearity and good
power capability and efficiency.
HEATSINKING
When operating this fixture please provide adequate heat-
sinking for the device. Excessive heating of the device will
prevent repeating of the included measurements.
REFERENCE DESIGN LIBRARY TERMS
AND CONDITIONS
NONLINEAR SIMULATION
Freescale is pleased to make this reference design
available for your use in development and testing of your
own product or products, without charge. The reference
design contains easy-to-copy, fully functional amplifier
designs. Where possible, it consists of “no tune” distrib-
uted element matching circuits designed to be as small as
possible, includes temperature compensated bias circuit-
ry, and is designed to be used as “building blocks” for our
customers.
To aid the design process and help reduce time to market
for our customers, Freescale provides device models for
several commercially available harmonic balance simulators.
Our model Library is available for all major computer platforms
supported by these simulators. For details on the RF model
library and supported harmonic balance simulators, go to the
