RF LDMOS Wideband Integrated

Power Amplifiers

The MD7IC2251N wideband integrated circuit is designed with on--chip

matching that makes it usable from 2110--2170 MHz. This multi--stage

structure is rated for 26 to 32 volt operation and covers all typical cellular

base station modulation formats.

• Typical Doherty Single--Carrier W--CDMA Characterization Performance:

Input Signal PAR = 9.9 dB @ 0.01% Probability on CCDF.

2. Refer to AN1977, Quiescent Current Thermal Tracking Circuit in the RF Integrated Circuit Family and to AN1987, Quiescent Current Control

for the RF Integrated Circuit Device Family. Go to http://www.freescale.com/rf. Select Documentation/Application Notes -- AN1977 or AN1987.

3. Peaking and Carrier orientation is determined by the test fixture design.
