pSemi Corporation 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. The UltraCMOS 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.
The PE42726 delivers best-in-class linearity across 5–1794 MHz with an 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 a 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 the overall isolation of two independent diplexers filter paths.
