Product Specification
PE4280
75 Ω SPDT CATV UltraCMOS™ Switch
DC—2.2 GHz
Product Description
The PE4280 is an UltraCMOS™ Switch designed for CATV
applications, covering a broad frequency range from DC up to
2.2 GHz. This single-supply SPDT switch integrates a two-pin
CMOS control interface. It also provides low insertion loss with
extremely low bias requirements while operating on a single 3 V
supply. In a typical CATV application, the PE4280 provides for
a cost effective and manufacturable solution when compared to
mechanical relays.
Features
• 75 Ω characteristic impedance
• Integrated 75 Ω 0.25 watt terminations
• CTB performance of 85 dBc
• High isolation 60 dB at 1 GHz
• Low insertion loss: typically 0.5 dB at
5 MHz, 1.1 dB at 1 GHz
• High input IP3: 50 dBm
The PE4280 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.
• CMOS two-pin control
• Single +3 V supply operation
• Low current consumption: 8 µA
• Unique all off terminated mode
• 4x4 mm QFN package
