Product Specification
PE43602
50 ? RF Digital Attenuator
Product Description
The PE43602 is a HaRP ? -enhanced, high linearity, 6-bit RF
Digital Step Attenuator (DSA) covering a 31.5 dB attenuation
range in 0.5 dB steps. This Peregrine 50 ? RF DSA provides
both a serial and parallel CMOS control interface. It maintains
high attenuation accuracy over frequency and temperature and
exhibits very low insertion loss and low power consumption.
Performance does not change with V DD due to on-board
regulator. This next generation Peregrine DSA is available in a
4x4 mm 24 lead QFN footprint.
The PE43602 is manufactured on Peregrine’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.
