ULTRACMOS RF DIGITAL STEP ATTENU

The PE43610 is a 50 Ohm, HaRP technology-enhanced, 6-bit RF digital step attenuator (DSA) that supports a wide frequency range from 9 kHz to 13 GHz. The PE43610 features glitch-safe attenuation state transitions, supports 1.8V control voltage and optional V_{SS_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 PE43610 provides an integrated digital control interface that supports both serial addressable and parallel programming of the attenuation. The PE43610 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 13 GHz. In addition, no external blocking capacitors are required if 0 VDC is present on the RF ports.

The PE43610 is manufactured on pSemi’s UltraCMOS® process, a patented variation of silicon-on-insulator (SOI) technology.
