Product Description
The AG604-89 is a general-purpose buffer amplifier that
offers high dynamic range in a low-cost surface-mount
package. At 900 MHz, the AG604-89 typically provides
21 dB of gain, +33.5 dBm OIP3, and +19.5 dBm P1dB.
The device combines dependable performance with
consistent quality to maintain MTTF values exceeding
1000 years at mounting temperatures of +85 qC and is
housed in a lead-free/green/RoHS-compliant SOT-89
industry-standard SMT package.
The AG604-89 consists of Darlington pair amplifiers using
the high reliability InGaP/GaAs HBT 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 AG604-89 will work for other various applications
within the DC to 2.7 GHz frequency range such as CATV
and WiMAX.

AG604-89G (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 qC reflow temperature) and leaded
(maximum 245 qC reflow temperature) soldering processes. The plating material on the leads is NiPdAu.

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

Product Marking
The AG604-89G will be marked with an
“A604G” designator with an alphanumeric lot
code marked below the part designator. The
obsolete tin-lead package is marked with an
“AG604” designator followed by an

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.
