New 9kHZ broadband 7-bit DSA offers high monotonicity

Now stocked by RFMW, Peregrine Semiconductor’s PE43711 is a 7-bit digital step attenuator capable of maintaining 0.25dB monotonicity through 4GHz. Operating to 6GHz, the PE43711 offers 0.5dB monotonicity through 5GHz and 1dB monotonicity through 6GHz. 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 4mm x 4mm QFN package, says the company.
