Product Description
The AG103 is a general-purpose gain block that offers good
dynamic range and low noise figure in a low-cost surface-
mount package. The combination of high OIP3 and tight
gain variation window makes it attractive for a multitude of
applications. The device combines dependable performance
with superb quality to maintain MTTF values exceeding
1000 years at mounting temperatures of +85
qC
and is
available in the environmentally-friendly lead-free/green
/RoHS-compliant SOT-89 package. All devices are 100%
RF & DC tested.
The AG103 uses a high reliability GaAs MMIC technology
and only requires DC-blocking and bypass capacitors, and
an inductive RF choke for operation. Internal matching
provides a 50 ohm input / output impedance minimizing the
number of required external components.
The AG103 GaAs MMIC amplifier is well suited for
wireless infrastructure such as NMT-450, homeland
security, and 2
nd
generation mobile infrastructure utilizing
the cellular band. In addition, the amplifier can be used for
applications in various IF frequency bands.
