HMC504LC4B v05.0918 GaAs HEMT MMIC LOW NOISEAMPLIFIER, 14 - 27 GHzEvaluation PCB T M E - S IS O W N O S - L R IE LIF P M A List of Materials for Evaluation PCB 122789 [1] Item Description The circuit board used in this application should use J1, J2 2.92mm PCB mount K-Connector RF circuit design techniques. Signal lines should have 50 Ohm impedance while the package ground J3 - J6 DC Pin leads and exposed paddle should be connected C1, C2 100 pF Capacitor, 0402 Pkg. directly to the ground plane similar to that shown. C3, C4 10,000pF Capacitor, 0603 Pkg. A sufficient number of via holes should be used to C5, C6 4.7 µF Capacitor, Tantalum connect the top and bottom ground planes. The U1 HMC504LC4B Amplifier evaluation board should be mounted to an appro- PCB [2] 122787 Evaluation PCB [3] priate heat sink. The evaluation circuit board shown [1] Reference this number when ordering complete evaluation PCB is available from Analog Devices, upon request. [2] Circuit Board Material: Rogers 4350 or Arlon 25FR [3] Due to the very high frequency operation of thisproduct a custom LC4B PCB footprint and solder stencilare required for this design. Performance shown in this data sheet was produced using this custom footprint. DO NOT USE Hittite’s standard LC4B footprint. Please contact Applications for details.
