CDKD-Type LTCC Multi-layered Differential Delay Lines

CDKD type delay line is an LTCC (Low Temperature Co-fired Ceramic) chip-type differential delay line, also due to ELMEC's own high-density monolithic LC structure. Crosstalk is reduced and, even for GHz-level high-speed signals, it can maintain stable, differential impedance and by connecting the 2 differential lines, can also be used as a 2x Td single-ended Delay Line. It is a RoHS-compliant component.
