Description
Description:PE43703 is a high linearity, 7-bit digital RF step attenuator, "DSA" with 0.25 dB steps to 31.75 dB attenuation range. The frequency range is from 9K-6GHz to achieve attenuation. This 50 ohm RF DSA provides parallel and serial CMOS control interfaces running on a single 5V power supply, and maintains high frequency and temperature attenuation accuracy. It also has a unique control interface that allows the user to select the initial attenuation state at power-up. With shielding shell and anti-reverse connection protection diode.
