PE43701
Overview
- HaRP™-enhanced UltraCMOS™ device
- Attenuation: 0.25 dB steps to 31.75 dB
- High Linearity: Typical +59 dBm IIP3 The PE43701 is a HaRP™-enhanced, high linearity, 7-bit RF Digital Step Attenuator (DSA). This highly versatile DSA covers a 31.75 dB attenuation range in 0.25 dB steps. The Peregrine 50Ω RF DSA provides a parallel or serialaddressable CMOS control interface. It maintains high attenuation accuracy over frequency and temperature and exhibits very low insertion loss and low power consumption. Performance does not change with Vdd due to on-board regulator. This next generation Peregrine DSA is available in a 5x5 mm 32-lead QFN footprint. The PE43701 is manufactured on Peregrine’s UltraCMOS™ process, a patented variation of silicon-on-insulator (SOI) technology on a sapphire substrate, offering the performance of GaAs with the economy and integration of conventional CMOS.
