AH22S

AH22S Product Features x 50 – 1000 MHz x ±0.2 dB Gain Flatness x +25 dBm P1dB x -74 dBc CTB / CSO +39dBmV/channel, 77 channels The Communications Edge TM Product Information High Dynamic Range CATV Amplifier Product Description The AH22S is a high dynamic range amplifier targeting cable TV markets. The combination of gain flatness, high linearity, and bandwidth makes it ideal for CATV distribution, cable modem, and laser diode driver applications. The device uses two matched devices and is ideal for operation in a push-pull configuration to achieve high second order linearity. A mature and reliable GaAs MESFET technology is employed to maximize linearity at low power dissipation. The dual amplifier is housed in an industry standard surface-mount SOIC-8 package with all devices being 100% RF and dc tested. This device is available in a lead-free/green/RoHS-compliant package with NiPdAu plating material on the leads. It is compatible with both lead-free and lead soldering processes.

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 through diameter of .25mm (.010” ) Add as much copper as possible to inner and outer layers near the part to ensure optimal thermal performance. To ensure reliable operation, device ground paddle-to-ground pad solder joint is critical. Add mounting screws near the part to fasten the board to a heatsink. Ensure that the ground / thermal via region contacts the heatsink. For optimal thermal performance, expose soldermask on backside where it contacts the heatsink. RF trace width depends upon the PC board material and construction. Use 1 oz. Copper minimum. If the PCB design rules allow, ground vias should be placed under the land pattern for better RF and thermal performance. Otherwise ground vias should be placed as close to the land pattern as possible. All dimensions are in mm. Angles are in degrees.
