Product Description
The AG603-89 is a general-purpose buffer amplifier that
offers high dynamic range in a low-cost surface-mount
package. At 900 MHz, the AG603-89 typically provides
18.5 dB of gain, +33 dBm Output IP3, & +19.5 dBm P1dB.
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.
The AG603-89 consists of Darlington pair amplifiers using
the high reliability InGaP/GaAs HBT technology process
technology and only requires DC-blocking capacitors, a
bias resistor, and an 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, and W-CDMA. In addition,
the AG603-89 will work for other various applications
within the DC to 3 GHz frequency range such as CATV
and fixed wireless.

Parameter Rating
Operating Case Temperature -40 to +85°C
Thermal Resistance, Rth (1) 154° C/W
Junction Temperature, Tjc (2) 145° 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
+5.16V, 75 mA at an 85°C case temperature. A
minimum MTTF of 1 million hours is achieved for
junction temperatures below 177 °C.
Product Marking
The AG603-89 will be marked with an
“AG603” designator. An alphanumeric lot
code (“XXXX-X”) is also marked below the
part designator on the top surface of the
package.
Tape and reel specifications for this part are
located on the website in the “Application

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.
