HMC383LC4 v05.0514 GaAs PHEMT MMIC MEDIUMPOWER AMPLIFIER, 12 - 30 GHzEvaluation PCB T M S - S R IE LIF P M R A E W O R & P A E LIN List of Materials for Evaluation PCB 122198 [1] Item Description The circuit board used in this application should use J1, J2 2.92 mm PCB mount K-connector RF circuit design techniques. Signal lines should have 50 Ohm impedance while the package ground J3, J4 DC Pin leads and exposed paddle should be connected C1 100 pF capacitor, 0402 pkg. directly to the ground plane similar to that shown. C2 1,000 pF Capacitor, 0603 pkg. A sufficient number of via holes should be used to C3 2.2µF Capacitor, Tantalum connect the top and bottom ground planes. The U1 HMC383LC4 Amplifier evaluation board should be mounted to an appro- PCB [2] 108535 Evaluation PCB priate heat sink. The evaluation circuit board shown [1] Reference this number when ordering complete evaluation PCB is available from Hittite upon request. [2] Circuit Board Material: Rogers 4350.
