ECG055C InGaP HBT Gain Block The Communications Edge TM Product Information Product Features • DC – 6 GHz • +18 dBm P1dB at 1 GHz • +34 dBm OIP3 at 1 GHz • 20.5 dB Gain at 1 GHz • 3.4 dB Noise Figure • Available in Lead-free / green SOT-86 Package Style • Internally matched to 50 Ω Product Description The ECG055C is a general-purpose buffer amplifier that offers high dynamic range in a low-cost surface-mount package. At 1000 MHz, the ECG055C typically provides 19.7 dB of gain, +34 dBm Output IP3, and +18 dBm P1dB. The ECG055C 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 low-cost, surface-mountable plastic lead-free/green/RoHS-compliant 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.

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.
