Evaluation Board

The HMC441LC3B can be evaluated with the Evaluation PCB 109712 available from Analog Devices, or the PCB needed for evaluation can be made with the use of the provided Gerbers. As with any RF design, the PCB used to evaluate the HMC441LC3B must use RF routing and placement techniques to enable the full potential of the RF power amplifier. This includes matching the input/output impedances, ensuring the input/output signal impedances are 50 Ω, the use of ground planes and plenty of stitching via, connecting coaxial connector shields to ground and mounting the PCB to a heatsink. The diagram below shows an example evaluation board demonstrating the use of decoupling capacitors, correctly spaced via and short input/output traces with guarding.
