CMOS antenna switch beats exotic alternatives
The PE4263 SP6T RF antenna switch is the latest innovation in the expanding RF product portfolio from Peregrine Semiconductor.
CMOS antenna switch is a first for dual-band GSM
The PE4261 is billed as the world's first flip-chip SP4T RF antenna switch for dual-band GSM handset applications.
Next-generation handsets now being developed incorporate triband WCDMA and quad-band Edge platforms, an architecture which demands seven radios in a single handset.
This has greatly complicated the RF front-end by more than tripling the high power signal paths engineered in today's quad-band Edge handsets.
Because switching signals to and from a duplexer and filter banks are used in these next-generation designs, the burden to the switching function becomes high.

CMOS switch goes straight to the antenna
The PE4268 SP6T RF antenna switch is a packaged complement to the PE4263 die announced last month.
The new applications require: very low insertion loss due to the signal going through two switch paths; very high linearity due to its WCDMA platform; an effective switch solution for four independent, simultaneous signal paths and up to 14 control states; and very high isolation of better than +55dB for critical paths.
Peregrine's UltraCMOS technology enabled the PE42110 to meet these specifications, making it the only device delivering an efficient solution to the combined triband WCDMA/quad-band EDGE RF switching requirement by demonstrating the ability to integrate multiple switching devices, onboard controllers, high reliability, ESD tolerance and exceptional RF performance.
The UltraCMOS -based PE42110 incorporates Peregrine's revolutionary HaRP technology enhancements to deliver exceptional harmonic results, linearity and overall RF performance:high linearity of +71dBm IP3 or -116dBm IMD3; low insertion loss of 0.35dB (typical); high isolation in excess of 70dB at critical paths; and monolithic integration of key elements including three control lines operating 12 independent paths.
"The UltraCMOS PE42110 demonstrates the ability of UltraCMOS to achieve RF front-end architectures and efficiencies that cannot be accomplished with any other technology", comments Rodd Novak, Vice-President of Marketing and Business Development.
"Peregrine has outdistanced itself from the competition and will continue to do so as RF front-ends demand higher levels of integration coupled with leading edge RF performance", he adds.
Peregrine's 50ohm PE42110 2.75V RF switch operates from 100 to 3000MHz and provides many additional features, including 1500V HBM ESD tolerance at all ports; onboard CMOS logic which facilitates 1.8 or 2.75V control; no blocking capacitors; and fast switch settling time.
