AG403-89G

DC - 6000 MHz Cascadable Gain Block

Qorvo's AG403-89G is a general-purpose buffer amplifier that offers high dynamic range in a low-cost surface-mount package. At 900 MHz, the AG403-89G typically provides 21 dB of gain, +31.5 dBm OIP3, and +18 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 AG403-89G 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. In addition, the AG403-89G will work for other various applications within the DC to 6 GHz frequency range such as CATV.
