Bill of Materials for Evaluation PCB It is recommended that the circuit board used in the application EV1HMC637ALP5E follows proper RF circuit design techniques. Signal lines must Item Description have 50 Ω impedance while the package ground leads and J1, J2 SRI SMA connector package bottom are connected directly to the ground plane J3, J4 2 mm Molex header similar to that shown in Figure 22. Ensure that a sufficient C1, C2 100 pF capacitor, 0402 package number of via holes are used to connect the top and bottom C3 to C6 1000 pF capacitor, 0603 package ground planes. The evaluation board thermal design must also C7 to C9 4.7 μF capacitor, tantalum be considered and mounted to an appropriate heat sink. The U1 HMC637ALP5E evaluation circuit board shown is available from Analog PCB1 109765 evaluation PCB Devices, Inc. upon request. 1 Circuit board material: Rogers 4350. Rev.
