v02.0112
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
6 Lead 2x2 mm SMT Package: 4 mm2
Electrical Specications, TA = +25° C, 50 Ohm system
Typical Applications
The HMC652LP2E - HMC655LP2E are ideal for:
• Fiber Optics
• Microwave Radio
• Military & Space
• Test & Measurement
• Scientic Instruments
• RF / Microwave Circuit Prototyping
The HMC652LP2E / 653LP2E / 654LP2E / 655LP2E
are a line of wideband xed 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 at
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.

The circuit board used in the nal application should
be generated with proper RF circuit design tech-
niques. Signal lines at the RF port should have 50
ohm impedance and the package ground leads and
exposed paddle should be connected directly to
the ground plane similar to that shown above. The
evaluation circuit board shown above is available
from Hittite Microwave Corporation upon request.
