PE4249 Datasheet - Peregrine Semiconductor

PE4249, SPST CATV MOSFET Switch

Product Description The PE4249 is a high-isolation MOSFET Switch designed for CATV

Features

* 75-ohm impedance switch
* Non-reflective at RF1, open reflective at RF2 when OFF
* 75-ohm (0.25 watt) termination
* High isolation: 85 dB at 5 MHz, 60 dB at 1 GHz
* Low insertion loss: 0.5 dB at 5 MHz, 0.8 dB at 1 GHz
* High input IP2: >80 dBm

Applications

* covering a broad frequency range from DC up to 1.3 GHz. This singlesupply SPST switch integrates a single-pin CMOS control interface, and is non-reflective at port RF1 and open reflective at port RF2 when commanded OFF. It also provides low insertion loss with extremely low bias requirements while
