The HMC650, HMC651, HMC652, HMC653, HMC654, HMC655, HMC656, HMC657 and HMC658 line of wideband fixed value 50 Ohm matched attenuator chips
The HMC650, HMC651, HMC652, HMC653, HMC654, HMC655, HMC656, HMC657 and HMC658 are a line of wideband fixed value 50 Ohm matched attenuator chips which offer relative attenuation levels of 0, 2, 3, 4, 6, 10, 15 and 20 dB respectively, and exhibit better than 15 dB return loss over the DC to 50 GHz frequency range. The HMC650 and HMC651 are through-line products with 0 dB attenuation and lengths of 20 and 26 mils respectively, which permits mechanical interchangeability with any other pad within the hybrid design. Designed to handle up to +25 dBm of RF input power, these passive through lines and attenuators are backside metallized with gold and suitable for eutectic or epoxy die attach in microstrip, hybrid and multi-chip module applications where extremely flat attenuation and excellent VSWR versus frequency are required. These attenuator chips may be purchased individually by their respective part number.
