CLTE-MW™ Laminates

2019-05-23
CLTE-MW™ laminates are ceramic fi lled, woven glass reinforced PTFE

composites. CLTE-MW laminates were developed to provide a cost

effective, high performance material for the circuit designer. This unique

laminate system is well suited for applications that have limitations

in thickness due to either physical or electrical constraints. The seven

available thickness options from 3 mils to 10 mils ensure that ideal signal

to ground spacing exists for today’s 5G and other millimeter wave designs.

In addition, a variety of copper foil options are available including rolled,

reverse treated ED, and standard ED. Resistive foil and metal plate options

are also available upon request.

The CLTE-MW laminates are reinforced with spread glass, which along with

a high fi ller loading help minimize the high frequency glass weave effects

on electromagnetic wave propagation. The woven glass reinforcement

also provides excellent dimensional stability. Other key features of the

laminate include low z-axis CTE (30ppm/°C) for excellent plated through

hole reliability, a low loss tangent of 0.0015 at 10 GHz to enable low

loss designs, and low moisture absorption of 0.03% to ensure stable

performance in a range of operating environments. Thermal conductivity

of 0.42 W/(m.

K) enables heat dissipation in aggressive designs along with

a high dielectric strength of 630 V/mil to ensure good z-axis insulation

between conductor layers. The UL94 V-0 fl ammability rating enables the

use of CLTE-MW laminates in commercial applications.

CLTE-MW laminates are well suited for a range of applications including

Amplifi ers, Antennas, Baluns, Couplers and Filters. Applicable markets

range from Commercial and Consumer to Defense and Aerospace.
