The PE4314 is a 75-ohm, 6-bit glitch-less RF digital step attenuator (DSA). This new DSA extends Peregrine’s existing glitch-less DSA portfolio to 75 ohms. It is a pin-for-pin compatible upgraded version of the PE4304, PE4307, PE4308 and PE43404 DSAs. The PE4314 covers a 31.5 dB attenuation range in a 0.5 dB step. It is capable of maintaining 0.5 dB monotonicity through 2.5 GHz. 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. It features glitch-less attenuation state transitions and supports 1.8V control voltage and an extended operating temperature range up to +105 °C. The PE4314 is ideal for wired broadband applications in cable/satellite customer premises equipment (CPE) and infrastructure equipment. View product details.
