Product Features

Package

Product Description

The AG403 is a general-purpose buffer amplifier that offers high

dynamic range in a low-cost surface-mount package. At 900 MHz,

the AG403 typically provides 20.5 dB of gain, +31 dBm Output

IP3, and +17 dBm P1dB. The device combines dependable

performance with consistent quality to maintain MTBF values

exceeding 100 years at mounting temperatures of +85

°C and is

housed in a SOT-86 and SOT-89 industry standard SMT packages.

The AG403 consists of Darlington pair amplifiers using the high

reliability InGaP/GaAs HBT technology process technology and

only requires DC-blocking capacitors, a bias resistor, and an

inductive RF choke for operation.

The broadband MMIC amplifier can be directly applied to various

current and next generation wireless technologies such as GPRS,

GSM, CDMA, W-CDMA, and UMTS. In addition, the AG403

will work for other various applications within the DC to 5 GHz

frequency range such as CATV and fixed wireless.
