Product Description
The AG303-63 is a general-purpose buffer amplifier that
offers high dynamic range in a low-cost surface-mount
package. At 900 MHz, the AG303-63 typically provides
20.5 dB gain, +26 dBm OIP3, and +14 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-363 industry standard
SMT package.
The AG303-63 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 AG303-63 will work for other various applications
within the DC to 6 GHz frequency range such as CATV
and WiMAX.
