EVALUATION BOARD

The HMC7950 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 evaluation board and populated components are designed

to operate over the ambient temperature range of −40°C to

+85°C. For the proper bias sequence, see the Applications

Information section.

The evaluation board schematic is shown in Figure 41. A fully

populated and tested evaluation board, shown in Figure 40, is

available from Analog Devices, Inc., upon request.
