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 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 2nd generation mobile infrastructure utilizing
the cellular band. In addition, the amplifier can be used for
applications in various IF frequency bands.

Notes:
1. The amplifier should be connected directly to a +5 V regulator; no dropping resistor is required.
2. If no DC signal is present at the input, C1 can be removed. The input is internally grounded in the amplifier.
3. C2, C3, C5, & R1 are not used in the circuit. R2 is shorted across with 0 Ω in the circuit. These placeholders shown in

AG103
High Dynamic Range Gain Block Product Information
AG103-G (Green / Lead-free SOT-89 Package) Mechanical Information
This package is lead-free/Green/RoHS-compliant. It is compatible with both lead-free (maximum 260 °C reflow temperature) and leaded
(maximum 245 °C reflow temperature) soldering processes. The plating material on the leads is NiPdAu.

Thermal Specifications
Parameter Rating
Operating Case Temperature -40 to +85 °C
Thermal Resistance, Rth (1) 59 °C / W
Junction Temperature, Tj (2) 129 °C
1. The thermal resistance is referenced from the hottest
part of the junction to the ground tab (pin 4).
2. This corresponds to the typical biasing condition of
+5V, 150 mA at an 85 °C case temperature. A
minimum MTTF of 1 million hours is achieved for
junction temperatures below 160 °C.
Product Marking
The AG103-G will be marked with an
“103G” designator. An alphanumeric lot
code (“XXXX-X”) is also marked below the
part designator on the top surface of the
package. The obsolete tin-lead package is
marked with an “AG103” designator
followed by an alphanumeric lot code.
Tape and reel specifications for this part are
located on the website in the “Application
Notes” section.

Mounting Config. Notes
1. Ground / thermal vias are critical for the proper
performance of this device. Vias should use a .35mm
(#80 / .0135”) diameter drill and have a final plated
thru diameter of .25 mm (.010”).
2. Add as much copper as possible to inner and outer
layers near the part to ensure optimal thermal
performance.
3. Mounting screws can be added near the part to fasten
the board to a heatsink. Ensure that the ground /
thermal via region contacts the heatsink.
4. Do not put solder mask on the backside of the PC board
in the region where the board contacts the heatsink.
5. RF trace width depends upon the PC board material
and construction.
6. Use 1 oz. Copper minimum.
7. All dimensions are in millimeters (inches). Angles are
in degrees.
