AGR09085E
85 W, 865 MHz—895 MHz, N-Channel E-Mode, Lateral MOSFET
Introduction
The AGR09085E is a high-voltage, laterally diffused
metal oxide semiconductor (LDMOS) RF power tran-
sistor suitable for cellular band, code division multiple
access (CDMA), global system for mobile communi-
cation (GSM), enhanced data for global evolution
(EDGE), and time division multiple access (TDMA)
single and multicarrier class AB wireless base station
amplifier applications. This device is manufactured
on an advanced LDMOS technology offering state-
of-the-art performance, reliability, and best-in-class
thermal resistance. Packaged in an industry-stan-
dard package incorporating internal matching and
capable of delivering a minimum output power of
85 W, it is ideally suited for today's RF power ampli-
fier applications.

* Stresses in excess of the absolute maximum ratings can cause
permanent damage to the device. These are absolute stress rat-
ings only. Functional operation of the device is not implied at
these or any other conditions in excess of those given in the
operational sections of the data sheet. Exposure to absolute
maximum ratings for extended periods can adversely affect
device reliability.

* Although electrostatic discharge (ESD) protection circuitry has
been designed into this device, proper precautions must be
taken to avoid exposure to ESD and electrical overstress (EOS)
during all handling, assembly, and test operations. Agere
employs a human-body model (HBM), a machine model (MM),
and a charged-device model (CDM) qualification requirement in
order to determine ESD-susceptibility limits and protection
design evaluation. ESD voltage thresholds are dependent on the
circuit parameters used in each of the models, as defined by
JEDEC's JESD22-A114B (HBM), JESD22-A115A (MM), and
JESD22-C101A (CDM) standards.
Caution: MOS devices are susceptible to damage from elec-
trostatic charge. Reasonable precautions in han-
dling and packaging MOS devices should be
observed.
