In order for the prescaler to work properly, several conditions need to be adhered to. It is crucial that pins 1, 2 and 5 be supplied with a bypass capacitor to ground. In addition, the output signal (pins 6) needs to be ac coupled via an external capacitor as shown in the test circuit below. Description RF Input RF Output. The ground pattern on the board should be made as wide as possible to minimize ground impedance. Table 3.

Evaluation Board Layouts Peregrine Specification 101/0186 The Ceramic SOIC Prescaler Evaluation Board was designed to help customers evaluate the PE9308 divide-by-4 prescaler. On this board, the device input (pin 3) is connected to the SMA connector J2 through a 50 Ω transmission line. The device output (pin 6) is connected to SMA connector J3 through a 50 Ω transmission line. J1 provides DC power to the device via pin 1,2,4,5,7,8.Multiple decoupling capacitors (C4,5,8,9=10pF, C3,6,7,10=0.01uF) are used. It is the responsibility of the customer to determine proper supply decoupling for their design application. The board is constructed using 4 layers. The top and bottom layers are comprised of Rogers low loss 4350 material having a core thickness of 0.010"; while the internal layers are comprised of FR-4. The overall board thickness is 0.062".
