Product Description

The AG203-86 is a general-purpose buffer amplifier that

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

package. At 900 MHz, the AG203-86 typically provides

19.5 dB gain, +21 dBm OIP3, and +8 dBm P1dB. The device

combines dependable performance with consistent quality to

maintain MTTF values exceeding 100 years at mounting

temperatures of +85

qC & is housed in a SOT-86 (micro-X)

industry-standard SMT lead-free/green/RoHS-compliant

package.

The AG203-86 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 AG203-86 will work for other various applications

within the DC to 6 GHz frequency range such as CATV

and fixed wireless.
