PRELIMINARY SPECIFICATION
PE9304
Rad Hard for Space Applications
1- 7 GHz Low Power CMOS
Divide-by-2 Prescaler
Features
Fixed divide ratio of 2

Immunity
The PE9304 is a high-performance CMOS prescaler with
a fixed divide ratio of 2. Its operating frequency range is
1GHz to 7GHz. The PE9304 operates on a nominal 3 V
supply and draws only 13.5mA. It is packaged in a small
8-lead ceramic SOIC and is ideal for frequency scaling
and clock generation solutions.
The PE9304 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 PE9304 divides a 1GHz 7GHz input signal
by a factor of two thereby producing an output
frequency at half the input frequency. To work
properly at higher frequencies, the input and
output signals (pins 2 & 7) must be AC coupled
via an external capacitor, as shown in the test
circuit in Figure 7.
The ground pattern on the board should be made
as wide as possible to minimize ground
impedance.

Evaluation Kit Operation
The Ceramic SOIC Prescaler Evaluation Board was
designed to help customers evaluate the PE9304
divide-by-2 prescaler. On this board, the device
input (pin 2) is connected to the SMA connector J1
through a 50 transmission line. A series
capacitor (C3) provides the necessary DC block for
the device input. A value of 2.2pF was used for the
evaluation board; other applications may require a
different value.
The device output (pin 7) is connected to SMA
connector J3 through a 50 transmission line. A
series capacitor (C1) provides the necessary DC
block for the device output. This capacitor value
must be chosen to have low impedance at the
desired output frequency of the device. A value of
2.2pF was chosen for the evaluation board.
J2 provides DC power to the device via pin 1. Two
decoupling capacitors (C2=1000pF, C10=100pF)
are included on this trace. It is the responsibility of
the customer to determine proper supply decoupling
for their design application.
The board is constructed using 4 layers. The top
and bottom layers are comprised of Rogers low loss
4350 material having a core thickness of 0.010";
while the internal layers are comprised of FR-4.
The overall board thickness is 0.062".
