PE42726 Delivers the Best-in-Class Harmonics and Spurious Performance for Cable Industry Standard DOCSIS 3.1 and Beyond

SAN DIEGO – June 22, 2021 – pSemi® Corporation, a Murata company focused on semiconductor integration, today introduces a DOCSIS 3.1-compliant switch that meets increased demands for faster download speeds, higher bandwidth and data throughput required for today’s home internet connections. ThUltraCMOS® PE42726 is a single-pole, double-throw (SPDT) radio frequency switch designed for use in cable broadband applications including DOCSIS 3.1 cable modems, set-top boxes and residential gateways. PE42726 delivers high linearity, excellent low-frequency harmonics performance and high surge immunity in the 5–1794 MHz band.

“As remote work has become mainstream, global cable operators are deploying higher data rates to meet increased usage and bandwidth demands over existing cable connections. pSemi offers a family of RF solutions for cable broadband, including patented linearity technology enhancements to maximize data rates. PE42726 is the industry’s highest linearity, lowest spurious noise RF switch delivering best-in-class harmonics for industry standard DOCSIS 3.1 and beyond.”

Product Features and Capability

The PE42726 delivers best-in-class linearity across the 5–1794 MHz frequency band with exceptional second and third harmonic performance of -121 dBc and -150 dBc, respectively, at the fundamental frequency of 17 MHz. These levels ensure the upstream transmit (Tx) signal keeps the downstream receive (Rx) frequency range free of any unwanted self-interference across the shared coax cable. This switch features low insertion loss of 0.3 dB at 1218 MHz and high isolation performance of 39 dB at 204 MHz to keep Tx signal loss very low and to help with overall isolation of two independent diplexer filter paths.

Additionally, the PE42726 can support the performance requirements of DOCSIS 4.0. The PE42726 is manufactured on pSemi’s patented UltraCMOS® process and offered in a 12-lead, 3 × 3 mm QFN package.
