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°C and is

available in both the standard SOT-89 package and the

environmentally-friendly lead-free/green/RoHS-compliant

and green 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 2nd generation mobile infrastructure utilizing

the cellular band. In addition, the amplifier can be used for

applications in various IF frequency bands.
