RFMW Ltd. announces design and sales support for Peregrine Semiconductor’s PE43711, a 7-bit digital step attenuator capable of maintaining 0.25 dB monotonicity through 4 GHz. Operating to 6 GHz, the PE43711 offers 0.5 dB monotonicity through 5 GHz and 1 dB monotonicity through 6 GHz.

Featuring “glitch-less” attenuation state transitions, the PE43711 is ideal for many broadband wireless applications including 3G/4G infrastructure, land mobile radio (LMR) and point-to-point communication systems.

The attenuator incorporates both parallel and serial programming interfaces including the capability to program an initial attenuation state at power up. Peregrine offers this silicon on insulator device in a 4 x 4 mm QFN package.
