Product Details

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.
