ECG008 Product Features • DC – 4 GHz • +24 dBm P1dB at 1 GHz • +40 dBm OIP3 at 1 GHz • 15 dB Gain at 1 GHz • 4.6 dB Noise Figure • Available in Lead-free / green SOT-89 Package Style • Internally matched to 50 Ω InGaP HBT Gain Block Product Description The ECG008 is a general-purpose buffer amplifier that offers high dynamic range in a low-cost surface-mount package. At 1000 MHz, the ECG008 typically provides 15 dB of gain, +40 dBm Output IP3, and +24 dBm P1dB. The ECG008 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 leadfree/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 ECG008 will work for other various applications within the DC to 4 GHz frequency range such as CATV and mobile wireless.

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. R1 and R2 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.

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.
