pSemi® Corporation announced the PE42727 UltraCMOS® SPDT RF Switch, a high-isolation solution optimized for next‑generation broadband cable applications. This announcement underscores pSemi’s continued investment in advanced RF integration technologies that enables for DOCSIS® 4.0 and future-generation broadband architectures.

The PE42727 is a HaRP™ technology‑enhanced SPDT RF switch designed for cable broadband applications operating from 5 MHz to 3.1 GHz. Engineered to meet DOCSIS 4.0 requirements, the PE42727 delivers high surge protection, best‑in‑class linearity, exceptional harmonic performance, low insertion loss and high isolation, supporting advanced modulation schemes in modern cable networks.
 
Key product benefits of the PE42727 include:  
  • Support for DOCSIS 3.0, 3.1 and 4.0 systems, enabling flexible broadband architectures for cable modems, set‑top boxes, residential gateways and cable broadband infrastructure
  • Provides exceptional harmonic performance, including –121 dBc second harmonic and –140 dBc third harmonic at 17 MHz
  • Low insertion loss of 0.16 dB at 85 MHz and 0.55 dB at 1794 MHz
  • High isolation of 64 dB at 85 MHz and 30 dB at 1794 MHz
  • Built on UltraCMOS process technology, delivering GaAs‑like RF performance with CMOS levels of integration and manufacturability
“Broadband access networks are evolving rapidly, and operators require RF solutions that deliver consistent linearity and signal integrity across increasingly wide bandwidths,” said Rodd Novak, vice president of Sales and Marketing, pSemi. “The PE42727 was engineered specifically to address DOCSIS 4.0 system requirements, giving our customers a reliable, high performance RF switch to support next generation cable deployments."
