PE43508

PE43508

UltraCMOS® RF Digital Step Attenuator

The PE43508 is a 50Ω, HaRP™ technology-enhanced, 6-bit RF digital step attenuator (DSA) that supports a wide frequency range from 9k to 55 GHz. The PE43508 features glitch-safe attenuation state transitions, supports 1.8V control voltage and optional VSS_EXT bypass mode to improve spurious performance, making this device ideal for test and measurement, point-to-point communication systems, and very small aperture terminals (VSAT).

The PE43508 provides an integrated digital control interface that supports both serial addressable and parallel programming of the attenuation. The PE43508 covers a 31.5 dB attenuation range in 0.5 dB and 1 dB steps. It is capable of maintaining 0.5 dB and 1 dB monotonicity through 55 GHz. In addition, no external blocking capacitors are required if 0 VDC is present on the RF ports. The PE43508 is manufactured on pSemi’s UltraCMOS® process, a patented variation of silicon-on-insulator (SOI) technology.
