PE9303
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.
