AG103
High Dynamic Range Gain Block Product Information
The Communications Edge
TM
Product Features
• 50 – 870 MHz
• 13 dB Gain
• 3 dB Noise Figure
• >+36 dBm OIP3
• +20 dBm P1dB
• Single +5 Bias Supply
• Internally matched to 50 Ω
• Lead-free/Green/RoHS-
compliant SOT-89 Package
• MTTF > 1000 years
Applications
• Mobile Infrastructure
• CATV / DBS
• Defense / Homeland Security
• NMT-450 Infrastructure
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 2
nd
generation mobile infrastructure utilizing
the cellular band. In addition, the amplifier can be used for
applications in various IF frequency bands.
