Product Specification PE43601 50 RF Digital Attenuator 6-bit, 15.75 dB, 9 kHz - 6.0 GHz Product Description Features The PE43601 is a HaRP-enhanced, high linearity, 6-bit RF HaRP-enhanced UltraCMOS device Digital Step Attenuator (DSA). This highly versatile DSA covers a 15.75 dB attenuation range in 0.25 dB steps. The Attenuation: 0.25 dB steps to 15.75 dB Peregrine 50 RF DSA provides a serial-addressable CMOS High Linearity: Typical +58 dBm IIP3 control interface. It maintains high attenuation accuracy over Excellent low-frequency performance frequency and temperature and exhibits very low insertion loss and low power consumption. Performance does not change 3.3 V or 5.0 V Power Supply Voltage with V due to on-board regulator. This next generation DD Fast switch settling time Peregrine DSA is available in a 5x5 mm 32-lead QFN footprint. Programming Modes: Direct Parallel The PE43601 is manufactured on Peregrines UltraCMOS process, a patented variation of silicon-on-insulator (SOI) Latched Parallel technology on a sapphire substrate, offering the performance Serial-Addressable: Program up to of GaAs with the economy and integration of conventional eight addresses 000 - 111 CMOS.
