PE4274
75Ω Terminated - 2.2 GHz SPDT
CATV UltraCMOS™ Switch
Product Description
Featuring - Unpowered Operation
Features
• Unpowered operational state
• All-Off terminated state
• CTB performance of 90dBc
• High isolation 63 dB at 1 GHz
The PE4274 is an SPDT UltraCMOS™ Switch designed for
Broadband applications such as CATV, DTV, Multi-Tuner
DVR (Digital Video Recorder), Set-top Box, PCTV and
Game Boxes. It offers high isolation and low insertion loss
in both a powered and a unique unpowered default state.
The PE4274 covers a broad frequency range from near DC
to beyond 2.2 GHz with a single positive supply and CMOS
control. The PE4274 provides a smaller, cost effective,
more reliable and manufacturable alternative to mechanical
relays in some set-top box applications.
• Low insertion loss: typically 0.5 dB at
5 MHz, 0.8 dB at 1 GHz
• CMOS two-pin control
• Single +3 volt supply operation
• 1 kV ESD
The PE4274 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.
• Low current consumption: 8 µA

Switching Frequency
The PE4274 has a maximum 25 kHz switching
rate when the internal negative voltage generator
is used (pin 18 = GND). The rate at which the
PE4274 can be switched is only limited to the
switching time if an external -3 V supply is
provided at (pin 18 = VSS).
Pad
Notes:
RF Ground Pad
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 V DC
requirement is met.
2. Pins 16 and 17 are the CMOS controls that set the four operating
states.
3. Connect pin 18 to GND to enable the negative voltage generator.
Connect pin 18 to VSS (-3V) to bypass and disable internal -3V supply
generator. See “Switching Frequency”.

Figure 4. Typical Application Block Diagram
The PE4274 provides the high isolation
required by FCC part 15.115 regulation
between the television antenna and the cable
plant. The advantage of the PE4274 is that
device isolation / thru performance is
unique feature makes the PE4274 ideal for set-top
box and VCR applications.
The PE4274 supports signal flow from RFC to
RF1 and RF2 termination in the unpowered state;
similar to the powered state with C1=High,
C2=Low.

Figure 14. Evaluation Board Layouts
Evaluation Kit
The SPDT Switch Evaluation Kit facilitates
customer evaluation of the PE4274 SPDT switch.
The RF common port is connected through a 75 ꢀ
transmission line to J2. Ports 1 and 2 are
connected through 75 ꢀ transmission lines to J1
and J3. A through line connects F connectors J4
and J5. This transmission line can be used to
estimate the PCB loss over the environmental
conditions. J6 provides DC and digital inputs to
the device.
The board is composed of a four metal layer FR4
material with a total thickness of 0.062”. The
transmission lines are hybrid microstrip/coplanar
waveguide with ground plane (28 mil core, 21 mil
width, 30 mil gap).
The provided jumpers short the control pins to
ground for logic low. With the jumper removed the
control input rises to VDD for logic high through the
1 Mꢀ pull up resistor. These resistors will draw
several microamps from VDD. They are not
required for normal operation.
