WIDEBAND FIXED ATTENUATOR FAMILY, DC - 25 GHz

HMC652LP2E / HMC653LP2E / HMC654LP2E / HMC655LP2E

v01.0811

General Description

Features

Functional Diagram

4 Attenuator Products:

2, 3, 4 & 6 dB Fixed Attenuation Levels

Wide Bandwidth: DC - 25 GHz

Excellent Attenuation Accuracy

Power Handling: +25 dBm

Typical Applications

The HMC652LP2E - HMC655LP2E are ideal for:

• Fiber Optics

• Microwave Radio

• Military & Space

• Test & Measurement

• Scientific Instruments

• RF / Microwave Circuit Prototyping

The HMC652LP2E / 653LP2E / 654LP2E / 655LP2E

are a line of wideband fixed value SMT 50 Ohm

matched attenuators which offer attenuation levels

of 2, 3, 4 and 6 dB respectively. These passive

attenuators are ideal for military, test equipment, and

other wideband applications where extremely flat

attenuation, and excellent VSWR vs. frequency are

required.

These wideband attenuators handle up to +25 dBm

of input power, and are compatible with high volume

surface mount manufacturing techniques.
