Product Description
The PE83501 is a high-performance dynamic UltraCMOS™
prescaler with a fixed divide ratio of 2. Its operating frequency
range is 400 MHz to 3.5 GHz. The PE83501 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 frequency scaling and
microwave PLL synthesis solutions.
The PE83501 is manufactured on Peregrine’s UltraCMOS™
process, a patented variation of silicon-on-insulator (SOI)
technology on a sapphire substrate, offering the performance
of GaAs with the economy and integration of conventional
CMOS.

Product Specification
Evaluation Kit
Evaluation Kit Operation
The MSOP Prescaler Evaluation Board was designed
to help customers evaluate the PE83501 Divide-by-2
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 15 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 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 47 pF 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.
