The PE43711B-Z is a 50 Ω, 7-bit RF digital step attenuator (DSA) from pSemi, designed for broadband wireless applications. It supports a wide frequency range from 9 kHz to 6 GHz, featuring glitch-less attenuation state transitions and a maximum attenuation of 31.75 dB.
This device offers flexible attenuation steps of 0.25 dB, 0.5 dB, and 1 dB. It maintains monotonicity of 0.25 dB up to 4 GHz, 0.5 dB up to 5 GHz, and 1 dB up to 6 GHz. The PE43711B-Z operates with a 1.8V control voltage and an extended operating temperature range up to +105 °C.
Manufactured on pSemi’s UltraCMOS® process, it utilizes HaRP™ technology enhancements for high linearity and excellent harmonics performance. The attenuator supports both parallel and serial programming interfaces, allowing for an initial attenuation state to be programmed at power-up. It is supplied in a 24-lead 4x4 mm QFN package.
Key applications include 3G/4G wireless infrastructure, land mobile radio (LMR) systems, and point-to-point communication systems.
