AH11

AH11 Product Features • 150 – 3000 MHz • +44 dBm OIP3 (balanced configuration) The Communications Edge TM Product Information High Dynamic Range Dual Amplifier Product Description The AH11 is a high linearity amplifier for use in digital communication systems. It combines low noise figure and high intercept point into a low-cost SMT solution. This device extends the linear efficiency advantages of WJ’s AH1 to higher power levels by combining two internally matched die. This dual-amplifier configuration allows for the optimal design of balanced or push-pull operation. The amplifier can also be used for single-ended operation in each branch of a diversity receive system. A mature and reliable GaAs MESFET technology is employed to maximize linearity while achieving low noise figure. The package is a thermally enhanced lead-free/ green/RoHS-compliant SOIC-8 package thus allowing the device to achieve an MTTF greater than 100 years at a case temperature of 85 °C. All devices are 100% RF and DC tested.

S21 and S11 can be improved in the band of interest with some slight input tuning. 3. 3OIP measured with two tones at an output power of +5 dBm/tone separated by 10 MHz. The suppression on the largest IM3 product is used to calculate the 3OIP using a 2:1 rule. Slight OIP3 degradation of about 2 dB is expected to occur at lower temperatures (from 25 ºC to –40 ºC).

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-toground 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.
