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

manufacturing technology, which provides the

performance of GaAs with the economy and

integration capabiliti es of c onv entional CMOS.

Performance Curves

Insertion Loss

Return Loss

Attenu ation State Accuracy

This Insertion Loss curve represent s the

Min/Max conditions for the “0” pass

state ver sus all proc essing and

temperatur e c onditions. The Min case

is at –40C with the “Fast” processing

conditions. The Max case is at +85C

with the “Slow” proc es si n

g

conditions.

All other combinations fall within that

band. T he typical 25C case is labeled

+25C TT .

This Return Loss set of curves

represents the combination of all Ret ur n

Loss cases for all attenuation settin

g

s.

All cases are better than –14dB Return

Loss at 4GHz.

The Attenuation Accur ac y curve with

verti c al axi s of +/- 1dB shows all st ates

bett er than +/ - 0.5dB to 2GHz and better

than +/- 0.8dB to 4GHz.

Compression

The P1dB curv e shows all stat es with a

P1dB compression at appr ox imately 23dB

input power. T he condi tions for this curve

are Vdd = +5.0v and Vss = 0v. For higher

P1dB compression values, supply V ss wit h

a negative v oltage as shown in the nex t

curve.

The P1dB curv e shows all stat es with a P 1dB

compression at appr ox imately 31dB input

power. The conditions for this curve are Vdd =

+5.0v and Vss = -5.0v.
