New RF Switch from Peregrine Semiconductor Optimizes Performance of Broadband Cable Systems

Peregrine Semiconductor Corporation (NASDAQ: PSMI), a
fabless provider of high-performance radio frequency integrated
circuits (RFICs), today announced availability of the PE42720
75-Ohm RF switch for broadband cable systems. Manufactured on
Peregrine’s UltraCMOS® technology, the HaRP™-enhanced single-pole,
double-throw (SPDT) switch features high linearity, leading
isolation performance and excellent video feedthrough – a
combination that is ideal for supporting higher data rates in cable
modem termination systems (CMTS), multi-service headends, cable
television (CATV) optical transceivers, fiber hubs, optical network
terminals, and CATV amplifier modules.
Optimized for high linearity and isolation performance, the
PE42720 supports increasing data rates as required by the industry
transition to DOCSIS 3.1. High linearity minimizes distortion in
the cable network to support new modulation schemes such as
4096-QAM, while the ability to support high isolation between RF
ports minimizes unwanted signal interference. This combination is
critical as DOCSIS 3.1 relies on orthogonal frequency-division
multiplexing (OFDM) to improve spectral efficiency, allowing a 50%
increase in data rates up to 10Gb/s downstream and 1Gb/s
upstream.
“As the cable television market moves to OFDM to increase data
rates, manufacturers will need to make improvements in efficiency
in all parts of the system by reducing noise, intermodulation
distortions, and ingress,” said Mark Schrepferman, director of the
commercial and industrial product line with Peregrine’s High
performance Solutions Business Unit. “Peregrine has been supporting
these requirements for years in the wireless markets, and we are
pleased to bring the exceptional linearity and isolation
performance that can only be achieved using Peregrine’s UltraCMOS
technology and HaRP enhancements to broadband cable
applications.”
Peregrine’s new switch features high isolation performance of at
least 60dB across the entire broadband frequency range of 5MHz to 3
GHz (65dB at 1 GHz (typ) and 64dB at 2GHz). The device features
excellent video feedthrough of 5mVpp for reduced distortion, and
delivers low insertion loss (0.7 dB @ 1GHz and .8 dB @ 2 GHz),
which enhances overall system performance by reducing RF path noise
figure. In addition, high linearity with a CTB/CSO of -104 dBc
improves dynamic range of CATV systems. The PE42720 supports 1.8V
and 3.3V control logic and ESD performance of 2500V HBM on all
ports.
Development Tool Support
Peregrine Semiconductor also announced availability of the
PE42720 Evaluation Kit. The kit
can be ordered now, through Peregrine’s global direct sales
representatives and worldwide distribution partners.
Packaging, Pricing & Availability
The PE42720 is available now in volume production, supplied in a
4x4 mm 20-lead LGA package priced at $1.06 in 10K quantity orders.
Samples and volume-production quantities can be ordered today,
