Core Performance Features

At 10GHz, 23°C, and 50% relative humidity, this CLTE-XT PCB delivers exceptional electrical performance: a dielectric constant (DK) of 2.79–2.94 with an industry-leading tight tolerance of±0.03, ensuring consistent signal propagation across batches. 

The dissipation factor is an ultra-low 0.0010, minimizing circuit losses in high-frequency operations. 

Physically, it boasts superior stability with X/Y-axis CTE of 12.7/13.7 ppm/°C and Z-axis CTE of 40.8 ppm/°C, while its glass transition temperature (Td) of 539°C and moisture absorption of just 0.02% guarantee reliability in extreme thermal and humid environments. Additionally, a dielectric constant temperature coefficient of -8 ppm/°C ensures performance stability as operating temperatures fluctuate.

Key Benefits

1) Enhanced Reliability: Premium via plating ensures long-term plated through-hole (PTH) integrity, reducing field failures.

2) Batch Consistency: Repeatable lot-to-lot performance simplifies mass production and quality control.

3) Balanced Performance: Low circuit losses are achieved without compromising dimensional stability, a critical advantage for high-precision designs.

4) System Compatibility: Stable dielectric constant across temperatures reduces mechanical stress when integrated with ceramic active devices, boosting overall system reliability.

Typical Applications

This CLTE-XT high frequency PCB is the ideal choice for: 

• Advanced Driver Assistance Systems (ADAS) 
• Patch antennas, phased array antennas, power amplifiers
• Ground-based/airborne communications and radar systems—where signal integrity, temperature resilience, and dimensional stability are non-negotiable.
