SOT-86 packages. A SOT-89 version is also available as
the ECG055B. All devices are 100% RF and DC tested.
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 ECG055C will work for other various applications
within the DC to 6 GHz frequency range such as CATV
and fixed wireless.

Product Information
ECG055C-G Mechanical Information
This package is lead-free/Green/RoHS-compliant. The plating material on the pins is annealed matte tin over copper. It is compatible with
both lead-free (maximum 260
°C
reflow temperature) and leaded (maximum 245
°C
reflow temperature) soldering processes.
Outline Drawing
Product Marking
The component will be marked with a two-digit
numeric lot code (shown as “XX”) followed
with an “S” designator on the top surface of the
package. The obsolete tin-lead package is
marked with a two-digit numeric lot code
followed with a “Y” designator; it may also
have been marked with a “Y” designator
followed by a two-digit 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.
