Key Features
- Integrated ground plane design minimizes crosstalk and signal skew, enabling high-speed differential signal transmission at 0.80 mm pitch across 20 positions
- Right-angle (L) board stacking orientation allows horizontal board-to-board mating for space-constrained multi-board system architectures
- Dual-row 20-position layout provides 40 total contacts in a compact 0.788" x 0.235" body for high-density signal routing
Applications
The QTE-020-05-L-D-A-K is used in high-speed board stacking applications such as server backplane assemblies, communication line cards, and FPGA daughter card interconnects where ground plane continuity is essential for signal integrity. Its 0.80 mm pitch and right-angle orientation enable compact horizontal stacking configurations in telecom and data center equipment. The 20-position dual-row layout supports mixed signal and power distribution across stacked PCB systems.

Frequently Asked Questions
Why does the QTE-020-05-L-D-A-K include a ground plane, and how does it benefit high-speed signal transmission?
The integrated ground plane in the QTE-020-05-L-D-A-K provides a continuous return path between the mated boards, reducing impedance discontinuities and crosstalk across the 20-position dual-row 0.80 mm pitch interface. This makes it suitable for high-speed differential signals operating at multi-Gbps data rates in FPGA, networking, and telecom board stacking designs.
How does the right-angle (L) orientation of the QTE-020-05-L-D-A-K affect board stacking layout?
The right-angle (L) orientation of the QTE-020-05-L-D-A-K enables horizontal board-to-board mating, where one PCB lies parallel to the mating board. With a body depth of 0.837" and breadth of 0.235", system designers can create compact horizontal multi-board assemblies without requiring vertical Z-height clearance typical of vertical stacking connectors.
For a backplane design needing 20 high-speed signals per site, how does QTE-020-05-L-D-A-K compare to 0.50 mm pitch alternatives?
At 0.80 mm pitch, the QTE-020-05-L-D-A-K offers wider contact spacing than 0.50 mm alternatives, providing better mechanical robustness and easier PCB routing for 20 differential signals. The ground plane integration delivers signal integrity comparable to 0.50 mm high-speed connectors while the 0.04" hole board mounting maintains positional accuracy during wave or selective solder assembly.
