製品概要The HMC8500 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 heatsink 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 circuit board to heatsink attachment.
The evaluation board and populated components are designed to operate over the ambient temperature range of −40°C to +85°C. During operation, attach the evaluation board to a temperature controlled plate to control the temperature of the HMC8500 during operation. For the proper bias sequence, see the Applications Information section of the data sheet.
