EVALUATION BOARD
The HMC8500PM5E evaluation board is a 2-layer board
fabricated with Rogers 4350 material and using layout
techniques recommended for high frequency RF designs.
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.
A fully populated and tested evaluation board, shown in Figure 45,
is available from Analog Devices, Inc., upon request.
