The PE4312 is a 50Ω, HaRP™ technology-enhanced 6-bit RF Digital Step Attenuator (DSA) designed for use in 3G/4G wireless infrastructure and other high performance RF applications. An integrated digital control interface supports both serial and parallel programming of the attenuation, including the capability to program an initial attenuation state at power-up. Covering a 31.5 dB attenuation range in 0.5 dB steps, it maintains high linearity and low power consumption from 1 MHz through 4 GHz.
The PE4312 Evaluation Kit (EVK) includes the application software and hardware required to control and evaluate the functionality of the DSA using a PC running the Windows operating system to control the USB interface board.
