PE4249 - SPST CATV MOSFET Switch

General Description

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

Key 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.
  • CMOS/TTL single-pin control.
  • Single +3 volt supply operation.
  • Extremely low bias: 33 µA @ 3V Figure 2. Pin Configuration VDD 1 GND 2 RF1 3 Exposed Solder Pad (bottom side) 6 R.

Product Description The PE4249 is a high-isolation MOSFET Switch designed for CATV 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 operating on a single 3-volt supply. In a typical CATV application, the high isolation PE4249 can replace bulky and expensive mechanical switches. The PE4249 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. Figure 1.
