Product Description
The AG603 is a general-purpose buffer amplifier that offers high
dynamic range in a low-cost surface-mount package. At 900 MHz,
the AG603 typically provides 17.6 dB of gain, +33.5 dBm Output
IP3, and +18.5 dBm P1dB. The device combines dependable
performance with consistent quality to maintain MTBF values
exceeding 100 years at mounting temperatures of +85°C and is
housed in a SOT-89 industry standard SMT package.
The AG603 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, W-CDMA, and UMTS. In addition, the AG603
will work for other various applications within the DC to 2.7 GHz
frequency range such as CATV and fixed wireless.
