Product Features
x x x x x x x x 50 – 1000 MHz +40 dBm OIP3 -71dBc CTB -48dBc CSO 3.5 dB Noise Figure 14.5 dB Gain +20 dBm P1dB Lead-free/Green/RoHS-compliant SOT-89 Package x Single +5 V Supply x MTTF > 100 years
Product Description
The AH2 is a general purpose, high dynamic range amplifier targeting cable TV markets. The combination of gain flatness, high linearity and bandwidth make it ideal for CATV distribution, cable modem and laser diode driver applications. The AH2 is designed for 75 ohm systems and can operate directly from a +5 Volt DC regulator. The device is manufactured using reliable GaAs MESFET technology and boasts an MTBF of >100 years at a mounting temperature of +85 °C. It is available in the environmentally-friendly lead-free/green/RoHS-compliant SOT-89 package. All devices are 100% RF and DC tested.

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.
