CDM-Type LTCC Chip Delay Line
The CDM-type Delay Line is an LTCC (Low-Temperature, Co-fired Ceramic) chip Delay Line. By removing one (1) line from the CDKD-type differential Delay Line, we have been able to accommodate a very compact overall area of only 5mm x 2.5mm. In addition, we have described a CDM/CDKD common land pattern on which the CDM-type should be mounted for delay times within a 3ns delay range, and on which the CDKD-type should be mounted as a single-ended Delay Line, with the 2 differential lines connected in series (CDKD 2-line connection), for delay times over 3ns. We provide a 0.1~10ns delay range using a CDM/CDKD common land pattern.

(1)* Actual (1) is the typical value when utilizing land pattern #1.
(2)* Actual (2) is the prospective value when utilizing land pattern #2, derived from EM Simulation.
(3)* The guaranteed value of -3dB passband is limited by the band width of the pin probe during product inspection.
