RFMW Ltd. announces design and sales support for Peregrine Semiconductor’s PE4314, a 75 ohm digital step attenuator (DSA) spanning a frequency range of 1 to 2500 MHz. The PE4314 offers 6-bit resolution with 0.5 dB steps providing 31.5 dB attenuation range.

Its low distortion characteristics and 75 ohm circuit optimization make it ideal for CATV and multi-carrier applications. And, this DSA features Peregrine’s Glitch-less technology reducing attenuation state transitions to <0.5 dB thereby reducing software overhead and cost.  

Supporting parallel and serial programming interfaces, the PE4314 allows flexible programming within AGC loops and operating from a 3.3 V supply requiring only 130 uA of current. So, this DSA helps reduce power consumption compared to similar competitive parts.

The 20-lead, 4 x 4 mm QFN package is pin-compatible with existing Peregrine DSAs.
