| AH3 * * * * * * The Communications Edge TM Product Information High Dynamic Range Gain Block Product Features 50 - 870 MHz +41 dBm OIP3 3 dB Noise Figure 13 dB Gain +20 dBm P1dB Lead-free/Green/RoHS-compliant SOT-89 Package * Single +5 V Supply * MTTF > 100 years Product Description The AH3 is a high dynamic range amplifier in a low-cost surface-mount package. The combination of low noise figure and high output IP3 at the same bias point makes it ideal for receiver and transmitter applications. The device combines dependable performance with superb quality to maintain MTTF values exceeding 100 years at mounting temperatures of +85 C. The AH3 is available in the environmentally-friendly lead-free/green/RoHS-compliant SOT-89 package. The broadband amplifier uses a high reliability GaAs MESFET technology and is targeted for applications where high linearity is required. In addition, the AH3 is internally matched for 50 ohms.

MSL / ESD Rating Land Pattern ESD Rating: Value: Test: Standard: ESD Rating: Value: Test: Standard: Class 1B Passes 500V to <1000V Human Body Model (HBM) JEDEC Standard JESD22-A114 Class IV Passes 1000V to <2000V Charged Device Model (CDM) JEDEC Standard JESD22-C101 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.
