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 circuit board to heat sink 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 HMC8500PM5E during operation. For the proper bias sequence, see the Applications Information section within the data sheet.
A fully populated and tested evaluation board is available from Analog Devices, Inc., upon request.
