HMC608LC4 v04.0617 GaAs pHEMT MEDIUMPOWER AMPLIFIER, 9.5 - 11.5 GHzEvaluation PCB T M R - S E W O R & P A E IN S - L R IE LIF P M A List of Materials for Evaluation PCB 112763 [1] Item Description The circuit board used in this application should use J1, J2 PC mount SMA connector RF circuit design techniques. Signal lines should have 50 Ohm impedance while the package ground J3 - J8 DC Pin leads and exposed paddle should be connected C1 - C6 100 pF capacitor, 0402 pkg. directly to the ground plane similar to that shown. C6 - C10 1,000 pF Capacitor, 0603 pkg. A sufficient number of via holes should be used to C11 - C15 2.2µF Capacitor, Tantalum connect the top and bottom ground planes. The U1 HMC608LC4 Amplifier evaluation board should be mounted to an appro- PCB [2] 112761 Evaluation PCB priate heat sink.
