Peregrine : Digital step attenuators offer unmatched flexibility

Peregrine Semiconductor Corporation has released three new UltraCMOS™ Digital Step Attenuators (DSAs) in the expansion of its popular 50Ω DSA line. Building on their high-performance predecessors, along with flexible serial and parallel interface logic these new HaRP™-enhanced devices also offer highly flexible attenuation options by covering a 31.5dB attenuation range in 0.5 dB or 1.0 dB steps.

The PE43502, PE43503 and PE43602 DSAs offer best-in-class linearity, outstanding attenuation accuracy and low Insertion Loss (IL). As with all UltraCMOS silicon-on-sapphire RFICs, there is no gate lag nor phase drift and the devices have exceptionally fast settling time, making them ideal for wireless broadband access applications such as TDE, WiMAX and TD-SCDMA (China’s 3G standard for mobile telecommunication), and for next-generation communication systems such as cellular base stations, repeaters, femtocells and power amplifier distortion cancelling loops.

These new 50-Ohm DSAs have an operating frequency range of near DC up to 6 GHz with exceptional low-frequency performance, Input IP3 of +58 dBm, superior noise immunity and outstanding ESD tolerance of 500V HBM. They work with two typical supply voltages of 3.3V or 5V with very low power consumption, allowing the use of a single devices in both the RF and IF radio sections to save board space.

Peregrine’s newest DSAs provide many additional features, including on-board CMOS logic which facilitates 2.75 V control, and a high- state at power-up (PUP). The devices are available in the ultra-compact, RoHS-compliant QFN 24-lead package (4x4x0.85 mm). All products are sampling now and are priced at PE43502: $2.14 (100K units); PE43503: $2.14 (100K units); and PE43602: $2.52 (100K units).

About UltraCMOS™ Technology and the HaRP Technology Innovation

UltraCMOS™ mixed-signal process technology is a patented variation of silicon-on-insulator (SOI) technology on a sapphire substrate providing with high yields and competitive costs. This technology delivers significant performance advantages over competing processes such as GaAs, SiGe BiCMOS and bulk silicon CMOS in applications where RF performance, low power and high levels of integration are paramount. The Company’s revolutionary HaRP™ technology further exploits the fundamental benefits of silicon-on-sapphire, enabling dramatic improvements in harmonic results, linearity and overall RF performance which today remain unmatched by any other RF process technology.
