Product Specification

PE4246

Absorptive SPST UltraCMOS™

RF Switch: DC - 5000 MHz

Product Description

The PE4246 RF Switch is designed to cover a broad range of

applications from DC to 5000 MHz. It is non-reflective at both

RF1 and RF2 ports. This SPST switch integrates a single-pin

CMOS control interface, and provides low insertion loss while

operating with extremely low bias from a single +3-volt supply.

In a typical application, the high isolation PE4246 can replace

multiple RF switches of lesser isolation performance. It is

offered in a small 3x3 mm DFN package.

Features

• Non-reflective 50-ohm RF switch

• 50-ohm (0.25 watt) terminations

• High isolation: 55 dB at 1000 MHz,

48 dB at 3000 MHz

• Low insertion loss: 0.8 dB at 1000 MHz,

0.9 dB at 3000 MHz

• High linearity: +33 dBm input 1dB

The PE4246 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.
