The PE4280 is an UltraCMOS™ Switch designed for CATV
applications, covering a broad frequency range from DC up to
2.2 GHz. This single-supply SPDT switch integrates a two-pin
CMOS control interface. It also provides low insertion loss with
extremely low bias requirements while operating on a single 3 V
supply. In a typical CATV application, the PE4280 provides for
a cost effective and manufacturable solution when compared to
mechanical relays.
The PE4280 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.

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.
Latch-Up Avoidance
Unlike conventional CMOS devices, UltraCMOS™
devices are immune to latch-up.

Notes:
1. RF pins 3, 8, and 13 must be at 0 VDC. The RF pins do not require DC
blocking capacitors for proper operation if the 0 VDC requirement is met.
2. Pins 16 and 17 are the CMOS controls that set the three operating
states.
3. Connect pin 18 to GND to enable the on-chip negative voltage generator.
Connect
pin 18 to V
SS
(-3 V) to bypass and disable internal -3 V supply
generator. Also, see paragraph “Switching Frequency.”
4. Customer can add external resistance to ground to change or modify
termination resistance.
Switching Frequency
The PE4280 has a maximum 25 kHz switching
rate when the internal negative voltage generator
is used (pin 18=GND). The rate at which the
PE4280 can be switched is only limited to the
switching time if an external -3 V supply is
provided at pin 18 (V
SS
).

Exceeding absolute maximum ratings may cause

Evaluation Kit
The SPDT Switch Evaluation Kit board was
designed to ease customer evaluation of the
PE4280 SPDT switch. The RFC port is
connected through a 75 Ω transmission line to J2.
Port 1 and Port 2 are connected through 75 Ω
transmission lines to J1 and J3. A through
transmission line connects F connectors J4 and
J5. 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 four metal layer
FR4 material with a total thickness of 0.062”. The
transmission lines were designed using a
coplanar waveguide with ground plane (28 mil
core, 21mil width, 30 mil gap).
J6 provides a means for controlling DC and digital
inputs to the device. The provided jumpers short
the package pin to ground for logic low. When
the jumper is removed, the pin is pulled up to V
DD
for logic high.
When the jumper is in place, 3 µA of current will
flow through the 1 MΩ pull up resistor. This extra
current should not be attributed to the
requirements of the device.
Proper PCB design is essential for full isolation
performance. This eval board demonstrates good
trace and ground management for minimum
coupling and radiation.
