pSemi Corporation, a Murata company, has announced the PE42727 UltraCMOS SPDT RF Switch. The 75 Ohm RF switch is designed for high-performance DOCSIS 4.0 and future-generation broadband cable applications. It operates from 5 MHz to 3.1 GHz and is a HaRP technology-enhanced device.
The PE42727 supports DOCSIS 3.0, 3.1, and 4.0 systems for use in cable modems, set-top boxes, residential gateways, and cable broadband infrastructure. It provides high surge protection, best-in-class linearity, exceptional harmonic performance, low insertion loss, and high isolation to support advanced modulation schemes.
Key specifications include:
- Second harmonic: –121 dBc at 17 MHz
- Third harmonic: –140 dBc at 17 MHz
- Insertion loss: 0.16 dB at 85 MHz and 0.55 dB at 1794 MHz
- Isolation: 64 dB at 85 MHz and 30 dB at 1794 MHz
The switch is built on UltraCMOS process technology, which combines GaAs-like RF performance with CMOS integration and manufacturability. Rodd Novak, Vice President of Sales and Marketing at pSemi, stated that the PE42727 was engineered to address DOCSIS 4.0 system requirements for consistent linearity and signal integrity across wide bandwidths.
PE42727 samples are available now, with commercial orders currently being accepted.
