  • WiMAX / WiBro Product Description The ECG004B is a general-pur pose 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 Dar lington pair amplifiers using the high reliability InGaP/Ga As 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 ca n be directly applied to various current and next ge neration wireless technologies such as GPRS, GSM, CDMA, and W-CDMA. In addition, the ECG004B will work for ot her various applications within the DC to 6 GHz frequency range such as CATV and mobile wireless.

The plating material on the leads is NiPdAu. It is compatible with both lead-free (maximum 260 °C reflow temperature) and leaded (maximum 245 °C reflow temperature) soldering processes. Outline Drawing Land Pattern Product Marking The component will be marked with an “E004G” designator with an alphanumeric lot code on the top surface of the package. The obsolete tin-lead package is marked with an “E004” designator followed by an alphanumeric lot code; it may also have been marked with a “D” designator followed by a 3-digit numeric lot code. Tape and reel specifications for this part are located on the website in the “Application Notes” section. MSL / ESD Rating ESD Rating: Class 1A Value: Passes between 250 and 500V Test: Human Body Model (HBM) Standard: JEDEC Standard JESD22-A114 MSL Rating: Level 3 at +260 °C convection reflow Standard: JEDEC Standard J-STD-020 Mounting Config. Notes 1. Ground / thermal vias are critical fo r 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 contact 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.
