This highly versatile DSA covers a 15.
5 dB attenuation range in 0.
5 dB steps.
The pSemi 50Ω RF DSA provides multiple CMOS control interfaces.
It maintains high attenuation accuracy over frequency and temperature and exhibits very low insertion loss and low power consumption.
Performance does not change with VDD due to on-board regulator.
This pSemi DSA is available in a 4x4 mm 24-lead QFN footprint.
The PE43650 is manufactured on pSemi’s UltraCMOS™ process, a patented variation of silicon-on-insulator (SOI) technology on a sapphire substrate, offering the performance of GaAs with the economy and integration of conventional CMOS.
