What is the Taconic TLX Series laminates?
TLX provides exceptional reliability across a broad spectrum of RF applications. This material is highly versatile, thanks to its dielectric constant (DK) range of 2.45 to 2.65, as well as its availability in various thicknesses and copper cladding options. It is particularly suitable for microwave designs with low layer counts. TLX PTFE fiberglass laminates are ideal for use in radar systems, mobile communications, microwave test equipment, microwave transmission devices, and RF components.
In the RF microwave substrate domain, TLX serves as a robust workhorse. The fiberglass reinforcement ensures mechanical stability in severe environments, such as resistance to creep for printed wiring boards bolted to housings that experience high vibration levels during space launches, high temperature exposure in engine modules, radiation resistance in space (refer to NASA’s website for low outgassing materials), antennas for warships operating in extreme maritime conditions, and as a substrate for altimeters subjected to wide temperature variations during flight.
The extensive range of available dielectric constants enables the production of couplers, splitters, combiners, amplifiers, and other critical RF components. Taconic is a global leader in RF laminates and high speed digital materials, offering an extensive portfolio of high frequency laminates and prepregs. These advanced materials are utilized in the fabrication of antennas, multilayer RF and high speed digital boards, interconnections, and devices.
TLX surpasses passive intermodulation (PIM) requirements in PCBs, achieving -153 dBc (measured between 880 and 960 MHz, 1710 and 1880 MHz, and 1920 and 2170 MHz at 20 W power) when processed with CL1/CLI cladding using state of the art processes and parameters.

Features of the Taconic TLX Series laminates
Low and stable Dk
With nominal Dk values ranging from 2.45 to 2.65 (depending on grade), The materials maintain tight control (±0.04) over dielectric constant at 10 GHz. This stability minimizes impedance variation and supports design consistency.
Excellent Mechanical & Thermal Performance
Designed to withstand harsh operating environments, The laminates deliver high thermal stability and mechanical durability, ensuring reliability in applications exposed to temperature fluctuations or physical stress.
Low Dissipation Factor (Df)
The laminates feature minimal signal loss (<0.0022 typical), making them ideal for high-efficiency RF/microwave circuits where energy conservation is paramount. Low DF values minimize signal loss, making TLX ideal for high frequency applications.
Low Moisture Absorption
The material’s hydrophobic nature ensures consistent electrical performance even in humid conditions, eliminating risks of Dk drift or signal loss due to moisture ingress. Minimal moisture absorption ensures stable electrical properties in humid environments, reducing the risk of performance degradation.
UL 94 V0 Flammability Rating
The material meets stringent flame-retardant standards, ensuring safety in mission-critical environments. All TLX Series laminates meet UL 94 V0 standards, ensuring self extinguishing behavior that aligns with global fire safety requirements for commercial and industrial electronics.
Superior Passive Intermodulation (PIM) Performance
Engineered for high power RF applications, TLX substrates demonstrate PIM levels lower than –160 dBc* when tested under standard two tone conditions. Such low intermodulation products are vital for maintaining signal integrity in cellular base stations, repeaters, and point to point radios.
Applications of the Taconic TLX Series laminates
TLX Series laminates empower designers across a broad spectrum of RF/microwave and high speed digital markets:
Antennas
From phased array panels to microstrip patch antennas, the low-loss and tightly controlled Dk of TLX ensures predictable radiation patterns and efficient power transfer. From 5G base stations to satellite communication systems, It’s low-loss properties and stable Dk ensure high gain, efficiency, and signal integrity.
Mixers, Splitters, Filters & Combiners
These components require precise electrical characteristics to ensure optimal signal processing and distribution, which TLX laminates deliver with excellence. Precision passive components benefit from TLX’s tight Dk tolerance and minimal insertion loss, enabling sharp frequency responses and reduced noise.
Passive Components
Power amplifiers, couplers, and resonators leverage the material’s thermal stability and PIM performance for reliable operation in demanding scenarios. Integrated passive devices (IPDs) including couplers and baluns rely on the material’s dimensional stability and low DF to achieve repeatable performance across production lots.
TLX Series laminates bridge the gap between high frequency performance and manufacturability, offering a unique blend of electrical, thermal, and mechanical properties. For engineers designing antennas, RF components, or low-layer-count microwave systems, TLX delivers the precision, reliability, and cost efficiency needed to stay ahead in competitive markets.
