PE83511
Product Specification
J2 provides DC power to the device. Starting from the
lower left pin, the second pin to the right (J2-3) is
connected to the device VDD pin (1). Two decoupling
capacitors (10 pF, 1000 pF) are included on this trace.
It is the responsibility of the customer to determine
proper supply decoupling for their design application.
Evaluation Kit
Evaluation Kit Operation
The PE83511 EK board was designed to ease
customer evaluation of Peregrine’s high performance
divide-by-2 Military Grade Prescaler. On this board,
the device input (pin 2) is connected via connector J1
and a 50 ꢀ transmission line. A series capacitor (C3)
provides the necessary DC block for the device input.
It is important to note that the value of this capacitance
will impact the performance of the device. A value of
1000 pF was found to be optimal for this board layout;
other applications may require a different value.

The device output (pin 7) is connected to connector J3
through a 50 ꢀ transmission line. A series capacitor
(C1) provides the necessary DC block for the device
output. Note that this capacitor must be chosen to
have low impedance at the desired output frequency
the device. The value of 1000 pF was chosen to
provide a wide operating range for the evaluation
board.

Peregrine Specification 101/0190
The board is constructed of a two-layer FR4 material
with a total thickness of 0.031”. The bottom layer
provides ground for the RF transmission lines. The
transmission lines were designed using a coplanar
waveguide above ground plane model with trace width
of 0.030”, trace gaps of 0.007”, dielectric thickness of
0.028”, metal thickness of 0.0014” and εr of 4.4. Note
that the predominate mode for these transmission lines
is coplanar waveguide.
