Bottom drawing 6/10 Doc ID 024115 Rev 1 EVAL-RHF330V1 5 Evaluation board description Evaluation board description The PCB is designed for 50-ohm generators and receivers. A 50-ohm calibration path can be used for high speed products. Capacitor C8 can be used to load the output. Capacitor C7 and resistor R5 can be used to stabilize the product. Pi resistors R7, R2, and R8 are used to adapt impedance between the output load and the hardware tool. For example, to load the device under test (DUT) with 150 Ω when the analyzer is 50 Ω input impedance, use the following equations for each respective resistor: ● R7 = 2.2 kΩ ● R2 = 130 Ω ● R8 = 82 Ω. A 100-nF and a 100-μF capacitor are soldered onto each supply. A third supply place is kept free in case an additional bypass capacitor is needed. Resistors (R) mounted on the board are placed to get a positive gain of two by the DUT as shown in Figure 7. Figure 7.
