Product Description

The PE43713 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, supports 1.8V

mode to improve spurious performance, making this device ideal for test and measurement (T&M).

The PE43713 is a pin-compatible upgraded version of the PE43703. 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 PE43713 covers a 31.75 dB attenuation range in 0.25 dB, 0.5 dB and 1dB steps. It is capable of maintaining

0.25 dB monotonicity through 4 GHz, 0.50 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.
