PE4271
SPST CATV UltraCMOS™ Switch
DC - 3000 MHz
Product Description
The PE4271 is a is a high-isolation Switch designed for CATV
applications, covering a broad frequency range from near DC
up to 3000 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 PE4271
provides for a cost effective and manufacturable solution vs.
mechanical relays.
Features
• Integrated 0.25 watt terminations
• CTB performance of 90 dBc
• High isolation: 85 dB at 5 MHz, 60 dB
at 1000 MHz
• Low insertion loss: 0.5 dB at 5 MHz,
0.70 dB at 1000 MHz
• High input IP2: >80 dBm
• CMOS/TTL single-pin control
• Single +3-volt supply operation
• Extremely low bias: 8 µA @ 3 V
• Available in a 6-lead DFN package
The PE4271 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.

When handling this UltraCMOS™ 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.

The PE4271 high isolation SPST CATV Switch is
designed to support CATV applications such as
premium channel service connect/disconnect switch
blocks. This function is typically performed by bulky
and expensive mechanical switches. The high
isolation characteristics (60 dB at 1 GHz, 85 dB at
5 MHz), high compression point, and an integrated
75 ꢀ (0.25 watt) input termination make the PE4271
an ideal, low cost solution.

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.
The control logic input pin (CTRL) is typically driven
by a 3-volt CMOS logic level signal, and has a
threshold of 50% of VDD. 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 VDD pin when the control logic

Peregrine Specification 101/0167 (with F connectors)
Evaluation Kit
The PE4271 EK board was designed to ease
customer evaluation of Peregrine’s high
performance SPST CATV MOSFET switch. RF1
is connected through a 75 ꢀ transmission line via
the top left F connector, J1. RF2 is connected
through a 75 ꢀ transmission line via the top right
F connector, J2. A 75 ꢀ through transmission line
is available via F connectors J3 and J4. This
transmission line can be used to estimate the loss
of the PCB over the environmental conditions
being evaluated. VDD is supplied via J6-2, while
the control logic voltage is supplied via J5-2. It is
the responsibility of the customer to determine
proper supply decoupling for their design
application. It has been observed that by
removing C1 and C2 from the evaluation board
has not shown to degrade RF performance.
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 εr of 4.6. Note that the predominate
mode for these transmission lines is coplanar
waveguide with a ground plane.
