The PE4232 is a is a high-isolation Switch designed for CATV
applications, covering a broad frequency range from near DC
up to 1300 MHz. This single-supply SPST switch offers a
single-pin CMOS control interface with industry leading CTB
performance. It also provides low insertion loss, high isolation
and extremely low bias requirements while operating on a
single 3-volt supply. In a typical CATV application, the PE4232
provides for a cost effective and manufacturable solution vs.
mechanical relays.
The PE4232 is manufactured on Peregrine's UltraCMOSTM
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.

Electrostatic Discharge (ESD) Precautions
When handling this UltraCMOSTM 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, UltraCMOSTM
devices are immune to latch-up.
Table 4. DC Electrical Specifications
Notes: 1. Both RF pins must be held at 0 V
DC
or require external DC
blocking capacitors
2. The exposed pad must be soldered to the ground plane for
proper switch performance.

Device Description
The PE4232 high isolation SPST CATV Switch is
designed to support CATV applications such as
premise disconnect of a CATV signal path. This
function is typically performed by bulky and
expensive mechanical switches. The high
isolation characteristics, high compression point,
and integrated 75-ohm terminations make the
PE4232 an ideal, cost effective and
manufacturable product of choice.
The control logic input pin (CTRL) is typically
driven by a 3-volt CMOS logic level signal, and
has a threshold of 50% of V
DD
. For flexibility to
support systems that have 5-volt control logic
drivers, the control logic input has been designed
to handle a 5-volt logic HIGH signal. (A minimal
current will be sourced out of the V
DD
pin when the
control logic input voltage level exceeds V
DD
.)

Notes: 1. CTRL accepts both CMOS and TTL voltage levels.
Absolute Maximum Ratings are those values
listed in the above table. Exceeding these values
may cause permanent device damage.
Functional operation should be restricted to the
limits in the DC Electrical Specifications table.
Exposure to absolute maximum ratings for
extended periods may affect device reliability.

Evaluation Kit
The SPST Switch Evaluation Kit board was
designed to ease customer evaluation of the
PE4232 SPST switch. The RF1 port is connected
through a 75
transmission line to the top left
BNC connector, J1. The RF2 port is connected
through a 75
transmission line to the BNC
connector on the top right side of the board, J2. A
through transmission line connects BNC
connectors J3 and J4. This transmission line can
be used to estimate the loss of the PCB over the
environmental conditions being evaluated.
The board is constructed of a two metal 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 model with
trace width of 0.021", trace gaps of 0.030",
dielectric thickness of 0.028", metal thickness of
0.0021" and
R of 4.3. Note that the predominate
mode for these transmission lines is coplanar
waveguide with a ground plane.
J5 provides a means for controlling DC and digital
inputs to the device. Starting from the lower left
pin, the second pin to the right (J5-3) is connected
to the device V
DD
input. The fourth pin to the right
(J5-7) is connected to the device CTRL input. It is
the responsibility of the customer to determine
proper supply decoupling for their design
application. Removing these components from
the evaluation board has not been shown to
degrade RF performance.
