UltraCMOS® RF Digital Step Attenuator

The PE43712 is a 50Ω, 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 1.8V control voltage and an extended operating temperature range to +105°C, making this device ideal for many broadband wireless applications.

The PE43712 is a pin-compatible upgraded version of the PE43601 and PE43701. An integrated digital control interface supports both serial addressable and parallel programming of the attenuation, including the capability to program an initial attenuation state at power-up.

The PE43712 cover 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.
