AGR19125E
125 W, 1930 MHz—1990 MHz, PCS LDMOS RF Power Transistor
Introduction
The AGR19125E is a 125 W, 28 V N-channel later-
ally diffused metal oxide semiconductor (LDMOS)
RF power field effect transistor (FET) suitable for
personal communication service (PCS)
(1930 MHz—1990 MHz), time-division multiple
access (TDMA), and single-carrier or multicarrier
class AB power amplifier applications.

Table 1. Thermal Characteristics
Table 2. Absolute Maximum Ratings*
* 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 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.
