Product Description
The AG303 is a general-purpose buffer amplifier that offers hig
h
dynamic range in a low-cost surface-mount package. At 900 MHz,
the AG303 typically provides 20.5 dB of gain, +27 dBm Outpu
t
IP3, and +13 dBm P1dB. The device combines dependable
p
erformance with consistent quality to maintain MTBF values
exceeding 100 years at mounting temperatures of +85°C and is
housed in a SOT-363 & SOT-86 industry standard SMT packages.
The AG303 consists of Darlington pair amplifiers using the hig
h
reliability InGaP/GaAs HBT technology process technology an
d
only requires DC-blocking capacitors, a bias resistor, and a
n
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 AG303
will work for other various applications within the DC to 5 GHz
frequency range such as CATV and fixed wireless.
