RT/duroid 5880LZ 1.2mm 1oz ENIG 6-Layer Ultra-Stable RF Circuit Board
Engineered for engineers who refuse to compromise on signal integrity, the PCBSync RT/duroid 5880LZ 6-Layer RF Circuit Board delivers ultra-stable performance from DC through millimeter-wave frequencies. Built on Rogers’ lightweight, ceramic-filled PTFE laminate with a 1.2mm finished thickness, 1oz copper, and a premium ENIG (Electroless Nickel Immersion Gold) surface finish, this 6-layer stackup is purpose-built for aerospace antennas, satellite payloads, phased-array radar, and 5G mmWave infrastructure where every dB and every gram counts.
Why RT/duroid 5880LZ?
RT/duroid 5880LZ holds the distinction of having the lowest dielectric constant of any commercially available copper-clad laminate — Dk 1.96 ±0.04 @ 10 GHz, with a dissipation factor as low as 0.0019. Unlike conventional PTFE/glass laminates, 5880LZ uses a proprietary hollow-ceramic-microsphere filler that yields a remarkably low-density, weight-sensitive substrate — ideal for airborne and space-grade RF modules. The Dk stays flat across 8 GHz to 40 GHz, eliminating frequency-dependent drift in wideband designs. With a Z-axis CTE of just 41 ppm/°C, plated-through-hole reliability is exceptional even under harsh thermal cycling.

Built for Mission-Critical RF Applications
This 6-layer ultra-stable RF board is the substrate of choice for engineering teams designing:
- Satellite communication feed networks and SATCOM transponders
- Aerospace and UAV phased-array antennas
- 5G mmWave base stations and small-cell radios
- Military radar and missile guidance systems
- Automotive 77 GHz radar modules
- High-Q microwave filters, couplers, and power dividers
The flat ENIG surface ensures excellent solderability for fine-pitch BGAs, QFNs, and 0201 SMD components, while the 6-layer construction provides dedicated RF, ground, and DC routing planes for clean isolation and predictable controlled impedance (typically ±5% or better with PCBSync impedance coupons on request).
