EMC Technology has expanded the RF product offering in its new line of surface mount chip terminations (CT) and chip resistors (CR). The new 0402 size surface mount chip devices are now available. The CT0402D (1,14 mm x 0,64 mm) termination achieves a power rating of 25 W and is rated for frequency performance up to 18 GHz and a maximum VSWR of 1,35. The 0402 case size resistor is also available with frequency performance up to 26,5 GHz and very low capacitance.
EMC offers a line of high power RF terminations and resistors using a CVD or diamond substrate. Also available are the 1,27 mm square CR0505D resistor which achieves a power rating of up to 40 W and the 2,54 mm square CR1010D resistor rated to 150 W. The 1,27 mm square CT0505D termination offers power handling capabilities up to 40 W, while the 3,30 mm x 2,54 mm CT1310D termination operates up to 150 W.
For weight restrictions in military and space flight applications, the CR and CT chips weigh only 0,015 grams in the 2,54 mm design while the 1,27 mm square design weighs only 0,003 grams. These terminations and resistors are lead-free and RoHS compliant, and are both wire bondable and solder capable in the same device using EMC Technology's new patent-pending gold finish metallisation.
