Product Description
The AG603-89 is a general-purpose buffer amplifier that
offers high dynamic range in a low-cost surface-mount
package. At 900 MHz, the AG603-89 typically provides
18.5 dB of gain, +33 dBm Output IP3, & +19.5 dBm P1dB.
The device combines dependable performance with superb
quality to maintain MTTF values exceeding 1000 years at
mounting temperatures of +85
°C and is available in the
environmentally-friendly lead-free/green/RoHS-compliant
SOT-89 package.
The AG603-89 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, and W-CDMA. In addition,
the AG603-89 will work for other various applications
within the DC to 3 GHz frequency range such as CATV
and fixed wireless.
