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.
All new Peregrine antenna switches incorporate this feature, enabling complete design flexibility.
Like its predecessor, the PE4261, the PE42612 offers the lowest total height and smallest footprint solution by implementing flip-chip packaging.
The use of advanced packaging technology reduces the PCB area and overall cost when compared with conventional wire bonding.
The 50ohm PE42612 complements the existing RF switch portfolio by incorporating unique UltraCMOS features: two-pin low-voltage CMOS logic control inputs; low TX insertion loss of 0.55dB at 900MHz and 0.70dB at 1.9GHz; high isolation of 39dB at 900MHz and 31dB at 1.9GHz; low harmonics (2fo = -82dBc and 3fo = -74dBc at 35dBm input power); 1500V HBM ESD tolerance; 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 all UltraCMOS antenna switches from Peregrine, this high-power device advances the industry, enabling new roadmaps to be drawn for next generation ASM designs where CMOS is directly connected to the antenna of a mobile handset.
UltraCMOS-based products provide superior performance, lower insertion loss and higher integration alternatives to pin-diodes or pHEMT switch/CMOS designs.
The PE42612 is slated for high-volume production in multiple facilities, including those of Peregrine's strategic partner, OKI Electric.
The device is priced at US $0.52 in 10,000-unit quantities.
