TRIQUINT AGR18045E

AGR18045E
45 W, 1.805 GHz—1.880 GHz, LDMOS RF Power Transistor
Introduction
The AGR18045E is a high-voltage, gold-metallized,
laterally diffused metal oxide semiconductor
(LDMOS) RF power field effect transistor (FET) suitable for global system 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 industrystandard package and is capable of delivering a minimum output power of 45 W, which makes it ideally
suited for today’s RF power amplifier applications.

* Stresses in excess of the absolute maximum ratings can cause
permanent damage to the device. These are absolute stress ratings 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. PEAK
Agere Devices
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 electrostatic charge. Reasonable precautions in handling and packaging MOS devices should be
observed.
