HRF-AT4510

15.5 dB, DC - 4GHz, 5 Bit Parallel Digital Attenuator

The Honeywell HRF-AT4510 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-AT4510 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. These attenuators are DC

coupled to improve lower operating frequency, frequency response and

reduce the number of DC bias points required.

FEATURES

• Very Low DC Power Consumption

• Attenuation In Steps From 0.5 dB To 15.5 dB

• Single Positive Power Supply Voltage

• Parallel Data Interface

• 50 Ohm Impedance

• DC-coupled, bi-directional RF path

• Space Saving VQFN Surface Mount Packaging

RF ELECTRICAL SPECIFICATIO NS @ + 25oC

Results @ VDD = 5.0 +/- 10%, VSS = 0 unless otherwise stated, Z0 = 50 Ohm s

Note 1 - Operation of this device beyond any of these parameters may cause permanent damage.

Note 2 - Although the HRF-AT4510 contains ESD protection circuitry on all digital inputs, precautions should be taken to

ensure that the Absolute Maximum Ratings are not exceeded.

Latch-Up: Unlike conventional CMOS digital attenuators, Honeywell's HRF-AT4510 is immune to latch-up.

CIRCUIT APPLICATION INFORMATION

These attenuators require a DC referen ce to ground. They may not operate properly when AC co upled on both the RF

input and output without a DC ground reference provided as part of the circuit. See Application Note AN311 at

www.honeywell.com/microwave.

NOTES

1. Pin 1 ID can be a combination of a dot and/or chamfer.

2. Dimensions are in millimeters.
