AGR18090E
90 W, 1.805 GHz—1.880 GHz, LDMOS RF Power Transistor
Introduction
The AGR18090E is a high-voltage, gold-metalized,
laterally diffused metal oxide semiconductor
(LDMOS) RF power transistor suitable for global sys-
tem for mobile communication (GSM), enhanced
data for global evolution (EDGE), and multicarrier
class AB power amplifier applications. This device is
manufactured using advanced LDMOS technology
offering state-of-the-art performance and reliability. It
is packaged in an industry-standard package and is
capable of delivering a typical output power of 90 W,
which makes it ideally suited for today’s wireless
base station RF power amplifier 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.
Table 3. ESD Rating
*
* 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 both a human-body model (HBM) 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-A114
(HBM) and JESD22-C101 (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.
