Product Description
The PE83502 is a high performance monolithic CMOS
prescaler with a fixed divide ratio of 4. Its operating
frequency range is 1.5 GHz to 3.5 GHz. The PE83502
operates on a nominal 3 V supply and draws only 12 mA.
It is packaged in a small 8-lead MSOP and is ideal for
microwave PLL synthesis solutions.
The PE83502 is manufactured in Peregrine’s patented
Ultra Thin Silicon (UTSi) CMOS process, offering the
performance of GaAs with the economy and integration
of conventional CMOS.

Evaluation Kit Operation
The MSOP Prescaler Evaluation Board was
designed to help customers evaluate the PE83502
Divide-by-4 Prescaler. On this board, the device
input (pin 2) is connected to connector J1 through a
50 Ω 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 15pF 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 Ω transmission line. A series
capacitor (C1) provides the necessary DC block for
the device output. Note that this capacitor must be
chosen to have a low impedance at the desired
output frequency the device. The value of 100pF
was chosen to provide a wide operating range for
the evaluation board.
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.
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.
The DEC pin (3) must be connected to a low
impedance AC ground for proper device operation.
On the board, two decoupling capacitors (C6 = 10
nF, C4 = 10 pF), located on the back of the board,
perform this function.
