The ECG003 is a general-purpose buffer amplifier that
offers high dynamic range in a low-cost surface-mount
package. At 1000 MHz, the ECG003 typically provides 20
dB of gain, +39 dBm Output IP3, and +24 dBm P1dB.
The ECG003 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 SOT-89 package. ECG003 is also
available in a 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 ECG003 will work for other various applications within
the DC to 6 GHz frequency range such as CATV and fixed
wireless.

1. The proper values for the components are dependent upon the intended frequency of operation.
2. The component values in the table below are contained on the evaluation board to achieve optimal broadband
performance.
3. R2 and R3 are shown in the circuit diagram to avoid potential instabilities. The configuration shown above assures
of unconditional stability with the use of the device. It is expected that linearity parameters (OIP3 and P1dB) to
degrade about only 0.5 dB, while overall gain will be about 2 dB less than the performance shown in page 1 and 2 of
this datasheet. Input and output return loss is expected to improve with the use of the I/O series resistances at 2 GHz.

The proper value for R1 is dependent upon the supply
voltage and allows for bias stability over temperature.
WJ recommends a minimum supply bias of +9 V. A
1% tolerance resistor is recommended.

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
