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 PE4261 is billed as the world's first flip-chip SP4T RF antenna switch for dual-band GSM handset applications.

This new landmark device provides antenna switch module (ASM) manufacturers the lowest total height and smallest footprint solution by implementing flip-chip packaging.

The use of advanced packaging technology reduces the PCB area by a factor of nine when compared to conventional wire bonding.

The 50ohm PE4261 complements the PE4263 RF switch with many unprecedented features, including: two-pin CMOS logic control inputs; low TX insertion loss of 0.55dB at 900MHz and 0.65dB at 1.9GHz; high isolation of 45dB at 900MHz and 40dB at 1.9GHz; low harmonics (2fo = -85dBc and 3fo = -72dBc at 35dBm input power); 1500V HBM ESD tolerance at all ports; an integrated CMOS decoder/driver and RX SAW overvoltage protection circuit.

The device offers linear operation from 100 to 3000MHz at 2.6V with fast switch settling time.

Further, the blocking capacitors typically found on pHEMT switches with positive control logic are not required for any UltraCMOS-based device.

Like the PE4263, this high-power device, developed on Peregrine's UltraCMOS technology, advances the industry past traditional milestones and enables new roadmaps to be drawn for next generation ASM designs.

For the first time ever, CMOS has been directly connected to the antenna of a GSM handset.

UltraCMOS-based products provide superior performance, lower insertion loss and higher integration alternatives to pin diodes or pHEMT switch/CMOS designs.

The PE4261 is slated for high-volume production in multiple facilities, including those of Peregrine's strategic partner, OKI Electric.

The device is priced at $0.52 in 10,000-unit quantities, and is available from Peregrine and its global distribution partner, Richardson Electronics.
