Product Description
The PE4273 RF Switch is designed for the TV tuner, PCTV, set
top box, DTV, DVR and general broadband applications. This
device offers industry leading broadband linearity, 1.5 kV ESD
tolerance and a simple CMOS interface. It offers a simple
alternative solution to pin diode and mechanical relay switches.
The PE4273 SPDT Broadband RF Switch 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.

6 V2 This pin supports two interface options:
Single-pin control mode. A nominal 3-volt
supply connection is required.
Complementary-pin control mode. A
complementary CMOS control signal
to V1 is supplied to this pin.
Note: 4. All RF pins must be DC blocked with an external series
capacitor or held at 0 VDC.

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.

Latch-Up Avoidance
Unlike conventional CMOS devices, UltraCMOS™
devices are immune to latch-up.
Electrostatic Discharge (ESD) Precautions
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.
