HMC442LC3B v03.0514 GaAs PHEMT MMIC MEDIUMPOWER AMPLIFIER, 17.5 - 25.5 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 109712 [1] The circuit board used in the final application Item Description should use RF circuit design techniques. Signal J1 - J2 PCB Mount SMA Connector lines should have 50 Ohm impedance while the J3 - J6 DC Pin package ground leads and exposed paddle should C1 - C2 100 pF Capacitor, 0402 Pkg. be connected directly to the ground plane similar to C3 - C4 1000 pF Capacitor, 0603 Pkg. that shown. A sufficient number of via holes should C5 - C6 2.2 µF Capacitor, Tantalum be used to connect the top and bottom ground U1 HMC442LC3B Amplifier planes. The evaluation board should be mounted PCB [2] 109710 Evaluation PCB to an appropriate heat sink. The evaluation circuit [1] Reference this number when ordering complete evaluation PCB board shown is available from Hittite upon request.
