PRELIMINARY SPECIFICATION
PE9303
3.5 GHz Low Power CMOS
Divide-by-8 Prescaler For
RAD-Hard Applications
Features
High-frequency operation:
1.5 GHz to 3.5 GHz
Fixed divide ratio of 8
Low-power operation: 14 mA
typical @ 3 V across frequency
Small package: 8-lead formed
flat pack
The PE9303 is a high performance monolithic CMOS
prescaler with a fixed divide ratio of 8. Its operating
frequency range is 1.5 GHz to 3.5 GHz. The PE9303
operates on a nominal 3 V supply and draws only 14 mA.
It is packaged in a small 8-lead pre-formed flat pack and
is ideal for space applications.
The PE9303 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 UTSi 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.
Latch-Up Avoidance
Unlike conventional CMOS devices, UTSi CMOS
devices are immune to latch-up.
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 & 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.

Evaluation Board Description
The PE9303 evaluation board is depicted in Figure
5. The input is driven into the RF In port while the
divided output is taken at Out 1. Both input and
output contain footprints for AC coupling capacitors
(C3 and C1 respectively). The power supply
connection is provided near the top of the
evaluation board, J2 Pin 1 as supply, J2 Pin 2 as
ground. In addition C2, C5, and C10 are
placeholders for power supply decoupling
capacitors. Placeholders C4, C6, and C8 are
needed for required bypass capacitors.
Note: C4 and C6 are located on the underside
of the evaluation board.
Figure 5. PE9303 Evaluation Board
Evaluation Board Test Setup
The PE9303 can be tested on the evaluation board
using the test setup shown in Figure 3 on page 3.
In the test setup, it is essential that the power
supply is properly decoupled and bypass
capacitors are used for pin 3. In addition, the input
and output need to be AC coupled.
Testing
The PE9303 Evaluation Board was measured prior
to shipment using the setup depicted in Figure 3.
Testing was performed at room temperature and
V
DD
= 2.85 V.
The input sensitivity plot for the PE9303 board is
included with the evaluation kit.
