Product Specification

Device Functional Considerations

The PE9303 takes an input signal frequency from

between 1.5 GHz to 3.5 GHz and produces an

output signal frequency one-fourth that of the

supplied input. In order for the prescaler to work

properly, several conditions need to be adhered

to. It is crucial that pin 3 be supplied with a

bypass capacitor to ground. In addition, the input

and output signals (pins 2 and 7, respectively)

need to be AC coupled via an external capacitor

as shown in the test circuit below.

The ground pattern on the board should be made

as wide as possible to minimize ground

impedance.
