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.
The new device was announced at the IEEE Microwave Theory and Technique (MTT) Society's Radio and Wireless Symposium held in San Diego.
It complements the SP6T and SP7T RF ICs launched last quarter from the company's next-generation UltraCMOS process with HaRP technology enhancements.
The newest device addresses the specific design requirements of next-generation dual-mode WCDMA handsets.
The switch offers the industry's most flexible combination of communication paths: two transmit ports that can be used for GSM/PCS/Edge, two transmit/receive ports that can be used for either WCDMA or as receive ports, and three symmetric receive ports.
This unique design allows engineering flexibility and ease of development not currently available in the high-throw RF switch arena.
Like its predecessors, the PE42671 is a highly integrated solution that simplifies and lowers the cost of RF designs by reducing overall part count in an ASM by as many as six devices and 13 wire bonds.
The PE42671 is also the world's most linear and usable SP7T switch with its exceptional harmonic performance (2fo = -88dBc and 3fo = -80dBc) IP3 of +68dBm; world-class 1.5kV ESD tolerance; 2.75V operating voltage and ultralow power consumption.
The PE42671 delivers world-class RF performance, offering TX-RX Isolation of +47dB at 900MHz and +40dB at 1900MHz; P1dB compression point of +41dBm; and 0.65 B of insertion loss at 900MHz.
On-chip CMOS decode logic facilitates both 1.8 and 2.75V three-pin CMOS control inputs, and the lack of blocking capacitors and on-chip SAW filter overvoltage protection devices ensure ease of integration.
The PE42671 die is priced at $0.75 in 25,000-unit quantities.
Orders are being taken for the devices which are available in die form and sampling to select customers directly from Peregrine.
