Short Description (for WooCommerce snippet)
A premium 4-layer Rogers RT/duroid 5880LZ RF PCB engineered for mmWave and high-frequency applications. Featuring a 1.0mm dielectric core, 1oz electrodeposited copper, and 10µ” immersion gold (ENIG) finish, this lightweight low-Dk laminate from PCBSync delivers exceptional signal integrity from sub-6 GHz through 40+ GHz — ideal for 5G, radar, and satellite designs.
Long Description
When millimeter-wave performance and weight savings both matter, RT/duroid 5880LZ is the substrate engineers reach for. This PCBSync-built 4-layer board pairs Rogers’ lightest PTFE laminate with a precision 1.0mm dielectric thickness, 1oz copper cladding, and a 10µ” gold ENIG surface finish — a configuration purpose-built for 5G mmWave antennas, automotive radar, satellite payloads, and aerospace RF modules where every dB of insertion loss counts.
What Makes RT/duroid 5880LZ Different
RT/duroid 5880LZ is a glass-microfiber-reinforced PTFE composite engineered with hollow ceramic microspheres. This proprietary filler system delivers the lowest dielectric constant in Rogers’ RT/duroid family — Dk 1.96 ± 0.04 at 10 GHz — along with a dissipation factor of just 0.0019 (typical). The result: faster signal propagation, wider trace widths at any given impedance, and ultra-low insertion loss well into Ku-band and beyond.
The “LZ” designation reflects its low Z-axis CTE. With X/Y/Z thermal expansion values closely matched to copper, plated-through-hole reliability stays rock-solid through aerospace and automotive temperature cycles. The hollow-sphere filler also makes the laminate noticeably lighter than standard 5880 — a meaningful advantage for airborne and space-bound hardware.

Why This Configuration Works
The 1.0mm core provides a stable, predictable platform for compact RF modules without sacrificing impedance control. 1oz copper strikes the ideal balance between fine-line etching capability and current handling, while the 10µ” ENIG finish delivers flat, oxidation-resistant pads — critical for fine-pitch BGAs, wire bonding, and multi-cycle lead-free reflow. A 4-layer stackup gives designers dedicated RF signal layers, solid ground reference planes, and DC routing room on one of the lowest-loss substrates Rogers manufactures.
Typical Applications
- 5G mmWave base station antennas (28 GHz / 39 GHz)
- 77 GHz automotive radar and ADAS sensors
- Satellite communication payloads and SATCOM terminals
- Phased-array and AESA radar systems
- Lightweight UAV and airborne radar electronics
- High-precision RF test and measurement fixtures
