UltraCMOS® PE42721 Switch Expands Peregrine’s
75-Ohm Portfolio to Offer Broadband-TV-System Manufacturers High
Isolation That Eliminates the Need for Multiple Tuner ICs
Peregrine Semiconductor Corp. (NASDAQ:PSMI), founder of RF SOI
(silicon on insulator) and pioneer of advanced RF solutions,
introduces the UltraCMOS PE42721 75-Ohm RF switch for designers of
digital TV (DTV) tuner modules, cable TV (CATV) signal switching
and distribution systems, multi-tuner digital video recorders
(DVRs) and set-top boxes. The switch is ideal for geographic
markets – such as China, Japan, Korea and Latin America – where
broadband-TV devices must accommodate multiple RF inputs for cable,
satellite and terrestrial reception while avoiding interference
between these signals. To achieve this, the PE42721 switch features
isolation so high that only this one tuner chip is needed in each
device, which reduces the overall tuner footprint and cost of the
system. Peregrine’s switch also delivers best-in-class linearity
and electrostatic-discharge (ESD) performance because it pairs the
high isolation with low insertion loss, which improves the signal
fidelity by reducing the signal-to-noise ratio (SNR).
“This latest extension of Peregrine’s 75-Ohm switch portfolio
offers broadband consumer-device and infrastructure designers a
cost- and space-saving RF switch that prevents signal distortion,”
says Mark Schrepferman, director of the commercial and industrial
product line with Peregrine’s High Performance Solutions Business
Unit.
Features, Packaging, Pricing & Availability
Peregrine’s PE42721 is a single-pole, double-throw (SPDT) switch
that balances the requirements for high isolation and low insertion
loss, while also reducing noise figure in broadband TV systems that
require switching between two RF sources. Peregrine’s new switch
provides isolation of greater than 55 dB across the entire, broad
frequency range from 5 MHz to 2.2 GHz. The switch features
excellent video feedthrough of 4 mVpp for reduced distortion. In
addition, it delivers low insertion loss (0.4 dB @ 220 MHz; 0.5 dB
@ 870 MHz; and 0.65 dB @ 2.2 GHz), which enhances overall system
performance by reducing the noise figure (NF) of the RF receive
path and improving the SNR. The high linearity (CTB/CSO of -99/-105
dBc) improves TV systems’ dynamic range, as well. The PE42721
supports 1.8 V and 3.3 V control logic, and high ESD performance.
Its packaging is RoHS compliant, 12-lead QFN, and it measures 3 x 3
mm. Samples and volume-production parts are available now and
priced at $0.45 each in 10K-quantity orders. Evaluation kit boards
are $95. For more detail, view the PE42721 press kit for images and
datasheet.
