What are the key features of QTE-020-08-FTL-D?
- 20-position dual-row Q Strip header at 0.80 mm pitch with integrated ground plane for controlled-impedance high-speed signal transmission
- High-frequency optimized design supports signal rates commonly used in multi-Gigabit serial link interfaces and differential pair routing
- Footprint-compatible Q Strip series enables consistent board-to-board signal integrity across compact high-density PCB assemblies
What is QTE-020-08-FTL-D used for?
The QTE-020-08-FTL-D is suited for high-speed board-to-board signal interfaces in networking line cards, storage controllers, and high-performance computing modules where signal integrity at multi-Gigabit rates is critical. Its integrated ground plane at 0.80 mm pitch reduces crosstalk between adjacent signal pairs, enabling clean differential signal transmission across the 20-position dual-row interface. Engineers use it in SERDES-based interface boards and FMC (FPGA Mezzanine Card) expansion designs.

Frequently Asked Questions
What pitch and position count does the QTE-020-08-FTL-D provide for high-speed designs?
The QTE-020-08-FTL-D has 20 positions at 0.80 mm pitch in a dual-row Q Strip header configuration. The 0.80 mm pitch allows compact routing of high-speed differential pairs on standard PCB layers while the 20-position count supports up to 10 differential signal pairs with adjacent ground contacts, enabling multi-Gigabit board-to-board links within a footprint under 10 mm in length.
How does the ground plane feature in QTE-020-08-FTL-D improve signal integrity?
The integrated ground plane in the QTE-020-08-FTL-D Q Strip header maintains controlled 50-ohm single-ended or 100-ohm differential impedance across the connector transition. By providing a continuous ground reference within 0.80 mm of each signal pin, it suppresses crosstalk between adjacent pins and reduces impedance discontinuities that would cause reflections at data rates above 1 Gbps, critical for SerDes and LVDS interfaces.
When is QTE-020-08-FTL-D preferred over a standard 0.80 mm pitch connector without ground plane?
Engineers prefer QTE-020-08-FTL-D when board-to-board interface data rates exceed 1 Gbps per channel or when differential pair crosstalk budgets are tight. Standard connectors without an integrated ground plane show 3 dB to 6 dB higher near-end crosstalk (NEXT) at 2 GHz to 5 GHz, which can cause bit errors in multi-Gigabit SerDes links. The Q Strip ground plane design addresses this without requiring additional ground via stitching on the PCB.
