ECG040 Product Features • DC – 4 GHz • +18.5 dBm P1dB at 1 GHz • +35 dBm OIP3 at 1 GHz • 16 dB Gain at 1 GHz • 5.5 dB Noise Figure • Available in Lead-free / green SOT-89 Package Style • Internally matched to 50 Ω InGaP HBT Gain Block Product Description The ECG040 is a general-purpose buffer amplifier that offers high dynamic range in a low-cost surface-mount package. At 1 GHz, the ECG040B typically provides 15.8 dB of gain, +35 dBm Output IP3, and +18.5 dBm P1dB. The ECG040 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 lowcost, 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 ECG040 will work for other various applications within the DC to 4 GHz frequency range such as CATV and mobile wireless.

Outline Drawing Product Marking The component will be marked with an “E040G” designator with an alphanumeric lot code on the top surface of the package. The obsolete tin-lead package is marked with an “E040” designator followed by an alphanumeric lot code; it may also have been marked with a “J” 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 Land Pattern ESD Rating: Value: Test: Standard: Class 1A Passes between 250 and 500V Human Body Model (HBM) 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 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.
