Product Description
The Honeywell HRF-AT4521 is a 5-bit digital
attenuator that is ideal for use in broadband
communication system applications that require
accuracy, speed and low power consumption. The
HRF-AT4521 is manufactured with Honeywell's
patented Silicon On Insulator (SOI) CMOS
manufacturing technology, which provides the
performance of GaAs with the economy and
integration capabilities of conventional CMOS.

Performance Curves
Insertion Loss
RF Out
This Insertion Loss curve represents
the Min/Max conditions for the “0”
pass state versus all processing and
temperature conditions. The Min
case is at –40C with the “Fast”
processing conditions. The Max case
is at +85C with the “Slow” processing
conditions. All other combinations fall
within that band. The typical 25C
case is labeled +25C TT.
