AG503-89

InGaP HBT Gain Block

Product Features

Green SOT-89package

Applications

Product Description

The AG503-89 is a general-purpose buffer amplifier that

offers high dynamic range in a low-cost surface-mount

package. At 900 MHz, the AG503-89 typically provides

21.5 dB of gain, +29 dBm OIP3, and +15.5 dBm P1dB.

The

device

combines

dependable

performance

with

consistent quality to maintain MTTF values exceeding

1000 years at mounting temperatures of +85

°C and is

housed

in

a

lead-free/green/RoHS-compliant

SOT-89

industry-standard SMT package.

The AG503-89 consists of Darlington pair amplifiers using

the high reliability InGaP/GaAs HBT 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, and W-CDMA. In addition,

the AG503-89 will work for other various applications

within the DC to 4 GHz frequency range such as CATV

and WiMAX.
