Product Description

The PE4314 is a 75

Ω HaRP™ technology-enhanced, 6-bit RF digital step attenuator (DSA) that supports a

frequency range from 1 MHz to 2.5 GHz. It features glitch-less attenuation state transitions and supports 1.8V

control voltage and an extended operating temperature range up to +105 °C, making this device ideal for

multiple wired broadband applications.

The PE4314 is a pin-compatible upgraded version of the PE4304, PE4307, PE4308 and PE43404. 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.

The PE4314 covers a 31.5 dB attenuation range in a 0.5 dB step. It is capable of maintaining 0.5 dB monoto-

nicity through 2.5 GHz. In addition, no external blocking capacitors are required if 0 VDC is present on the RF

ports.
