General Description

Features

Functional Diagrams

3 Attenuator Products:

10, 15, & 20 dB Fixed Attenuation Levels

Wide Bandwidth: DC - 25 GHz

Excellent Attenuation Accuracy

Power Handling: +25 dBm

6 Lead 2x2mm SMT Package: 4mm2

Electrical Specifications, T

A = +25° C, 50 Ohm system

Typical Applications

The HMC656LP2E - HMC658LP2E are ideal for:

• Fiber Optics

• Microwave Radio

• Military & Space

• Test & Measurement

• Scientific Instruments

• RF / Microwave Circuit Prototyping

The HMC656LP2E / 657LP2E / 658LP2E are a

line of wideband fixed value SMT 50 Ohm matched

attenuators which offer relative attenuation levels

of 10, 15 and 20 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.
