Product Description
The Honeywell HRF-AT4611 is a 6-bit digital
attenuator that is ideal for use in broadband
communication system applications that require
accuracy, speed and low power consumption. The
HRF-AT4611 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

(Note 2) Operation of this Device beyond any of these parameters may cause permanent damage.
Latch-Up: Unlike conventional CMOS digital attenuators, Honeywell's HRF-AT4611 is immune to latch-up.
.
ESD Protection: Although the HRF-AT4611 contains ESD protection circuitry on all digital inputs, conventional precautions should
be taken to ensure that the Absolute Maximum Ratings are not exceeded.

Serial Data Load
Serial data is shifted into the register on the rising edge of clock, MSB first. The OE falling edge must occur prior to
any additional rising clock edges. See the Electrical Spec Table for AC parameters.

Operation: Data on serial input D is clocked into internal registers on the low to high transition of the Clock signal (CK). The register
output is enabled when Output Enable (OE) is in the low state.
"0" = CMOS Low, "1" = CMOS High.
Evaluation Circuit Board
Honeywell's evaluation board provides
an easy to use method of evaluating the

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.

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.
