PE43704 UltraCMOS®, HaRP™ Attenuator Evaluation Board

The PE43704 is a HaRP™ technology-enhanced, high linearity, 7-bit 50 Ohm RF Digital Step Attenuator (DSA). It offers maximum power handling of 28 dBm up to 8 GHz and covers a 31.75 dB attenuation range in 0.25 dB, 0.5 dB, or 1.0 dB steps. The PE43704 is a pin-compatible version of PE43703. It provides multiple CMOS control interfaces and an optional external negative voltage supply feature. It maintains high attenuation accuracy over frequency and temperature and exhibits very low insertion loss and low power consumption. No blocking capacitors are required if DC voltage is not present on the RF ports.
