The PE43704B-Z from pSemi is a high-linearity, 7-bit RF digital step attenuator (DSA) designed for demanding RF applications. It features pSemi's HaRP™ technology enhancement and is manufactured on their UltraCMOS® process, which combines the performance of GaAs with the economy of CMOS.
This attenuator offers a wide attenuation range of 0 dB to 31.75 dB, available in 0.25 dB, 0.5 dB, or 1.0 dB steps. It supports a maximum operating frequency of 8 GHz and maintains high attenuation accuracy over varying frequencies and temperatures. Key electrical specifications include a typical insertion loss of 1.3 dB up to 2 GHz, a return loss of 20 dB up to 4 GHz, and high power handling capabilities of 28 dBm CW at 8 GHz.
The PE43704B-Z is housed in a 32-VFQFN exposed pad package, suitable for surface mounting. It supports multiple CMOS control interfaces, including direct parallel, latched parallel, serial, and serial addressable modes. The device operates with a supply voltage up to 5.5V and features ESD protection of 1.5kV HBM on all pins.
With its combination of high linearity, broad attenuation range, and robust performance, the PE43704B-Z is well-suited for various RF systems requiring precise signal level control.
