Product Specification
PE43702
50 ? RF Digital Attenuator
Product Description
The PE43702 is a HaRP ? -enhanced, high linearity, 7-bit RF
Digital Step Attenuator (DSA). This highly versatile DSA
covers a 31.75 dB attenuation range in 0.25 dB steps. The
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.
7-bit, 31.75 dB, 9 kHz - 4.0 GHz
