The PE43701 from Peregrine Semiconductor (pSemi) is a HaRP-enhanced, high linearity, 7-bit RF Digital Step Attenuator (DSA). This versatile DSA operates from 9 MHz to 4 GHz, providing a 31.75 dB attenuation range with fine 0.25 dB steps. It maintains high attenuation accuracy over frequency and temperature, exhibiting very low insertion loss (1.9 dB typical) and low power consumption.
The Peregrine 50 Ohm RF DSA features a parallel or serial-addressable CMOS control interface. Its performance is stable with Vdd due to an on-board regulator. The device is available in a 5x5 mm 32-lead QFN footprint. This part is now discontinued, with the PE43712 serving as its pin-compatible drop-in replacement.
Key electrical specifications include an impedance of 50 Ohms, a typical IIP3 of 59 dBm, and a typical input power for 1 dB loss of 5 dBm. The device is designed for applications requiring precise RF signal level control.
