PE3503
3500 MHz Low Power UltraCMOS™
Divide-by-8 Prescaler
Product Description
The PE3503 is a high performance monolithic UltraCMOS™
prescaler with a fixed divide ratio of 8. Its operating frequency
range is 1500 MHz to 3500 MHz. The PE3503 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.
Features
• High-frequency operation: 1500 MHz
to 3500 MHz
• Fixed divide ratio of 8
• Low-power operation: 12 mA typical
The PE3503 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.

Electrostatic Discharge (ESD) Precautions
When handling this UltraCMOS™ device, observe
the same precautions that you would use with
other ESD-sensitive devices. Although this device
contains circuitry to protect it from damage due to
ESD, precautions should be taken to avoid
exceeding the rating specified in Table 3.

Description
The PE3503 takes an input signal frequency from
1500 MHz to 3500 MHz and produces an output
signal frequency one-eighth 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 & 7, respectively) need to
be AC coupled via an external capacitor as shown
in the test circuit in Figure 7.

customer to determine proper supply decoupling for
their design application.
Evaluation Kit
Evaluation Kit Operation
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.
The MSOP Prescaler Evaluation Board was designed
to help customers evaluate the PE3503 Divide-by-8
Prescaler. On this board, the device input (pin 2) is
connected to connector J1 through 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 15 pF was found
to be optimal for this board layout; other applications
may require a different value.
Applications Support
If you have a problem with your evaluation kit or if you
have applications questions call (858) 731-9400 and
ask for applications support. You may also contact us

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 a low impedance at the desired output frequency
the device. The value of 100 pF was chosen to provide
a wide operating range for the evaluation board.
Figure 9. Evaluation Board Layouts
Peregrine Specification 101/0035
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
