Product Description
The ECG004B is a general-purpose buffer amplifier that
offers high dynamic range in a low-cost surface-mount
package. At 1000 MHz, the ECG004B typically provides
16 dB of gain, +28 dBm Output IP3, and +13.5 dBm P1dB.
The ECG004B 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 device is
ideal for wireless applications and is available in a low-
cost, surface-mountable lead-free/green/RoHS-compliant
SOT-89 package. 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 ECG004B will work for other various applications
within the DC to 6 GHz frequency range such as CATV
and fixed wireless.

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 p art 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.
