Product Description
The Honeywell HRF-AT4520 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-AT4520 is manufactured with Honeywell's
patented Silicon On Insulator (SOI) CMOS
HRF-AT4520 in LPCC™ Package
manufacturing
technology, which provides the
performance of GaAs with the economy and
integration capabilities of conventional CMOS.

(Note2) Operation of this Device beyond any of these parameters may cause permanent damage.
Latch-Up: Unlike conventional CMOS digital attenuators, Honeywells' HRF-AT4520 is immune to latch-up.
.
ESD Protection: Although the HRF-AT4520 contains ESD protection circuitry on all digital inputs, conventional precautions should be
taken to ensure that the Absolute Maximum Ratings are not exceeded.

Preliminary
Performance Curves
Insertion Loss
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.
Return Loss
This Return Loss set of curves
represents the combination of all Return
Loss cases for all attenuation settings.
All cases are better than –14dB Return
Loss at 4GHz.
Attenuation State Accuracy
The Attenuation Accuracy curve with
vertical axis of +/- 1dB shows all states
better than +/- 0.5dB to 2GHz and better
than +/- 0.8dB to 4GHz.

Preliminary
Compression
The P1dB curve shows all states with a
P1dB compression at approximately 23dB
input power. The conditions for this curve
are Vdd = +5.0v and Vss = 0v. For higher
P1dB compression values, supply Vss with
a negative voltage as shown in the next
curve.
The P1dB curve shows all states with a P1dB
compression at approximately 31dB input
power. The conditions for this curve are Vdd =
+5.0v and Vss = -5.0v.
