PE43711 UltraCMOS® Glitch-less Digital Step Attenuator

pSemi offers its PE43711 UltraCMOS RF digital step attenuator, in frequency ranges of 9 kHz to 6 GHz

Image of Peregrine PE43711 UltraCMOS Glitch-less Digital Step AttenuatorpSemi’s PE43711 is a 50 Ω, HaRP™ technology-enhanced, 7-bit RF digital step attenuator (DSA) that supports a broad frequency range from 9 kHz to 6 GHz. It features glitch-less attenuation state transitions and supports 1.8 V control voltage and an extended operating temperature range to +105°C, making this device ideal for many broadband wireless applications. The PE43711 is a pin-compatible upgraded version of the PE43502, PE43503, PE43602, and PE43702. An integrated digital control interface supports both serial and parallel programming of the attenuation, including the capability to program an initial attenuation state at power-up. The PE43711 covers a 31.75 dB attenuation range in 0.25 dB, 0.5 dB, and 1 dB steps. It is capable of maintaining 0.25 dB monotonicity through 4 GHz, 0.5 dB monotonicity through 5 GHz, and 1 dB monotonicity through 6 GHz. In addition, no external blocking capacitors are required if 0 VDC is present on the RF ports. The PE43711 is manufactured on Peregrine’s UltraCMOS process, a patented variation of silicon-on-insulator (SOI) technology on a sapphire substrate.
