  7. EVAL-HMC8500PM5E
    Evaluation Board & Kit
    The HMC8500PM5E evaluation board is a 2-layer board fabricated using Rogers 4350 and using best practices for high frequency RF design. The RF input and RF output traces have a 50 Ω characteristic impedance. The board is attached to a heat sink using an electrically and thermally conductive epoxy providing a low thermal and low dc resistance path. Components are mounted using SN63 solder allowing rework of the surface-mount components without compromising the …
