The HMC943APM5E evaluation board is a 2 layer board fabricated using Rogers 4350 and best practices for high frequency RF design. The RF input and RF output traces have a 50 Ω characteristic impedance. The circuit board is attached to a heat sink using SN96 solder and provides a low thermal 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, to control the temperature of the HMC943APM5E, attach the evaluation board to a temperature controlled plate.
