PCB Construction Details

Advantages

F4BTMS450 has a dissipation factor (Df) of 0.0015 at 10GHz, ensuring minimal signal loss, making it ideal for high-frequency applications such as radar, microwave circuits, and satellite communication systems.

The PCB offers a Dk of 4.5 ± 0.09 at 10GHz, ensuring consistent signal integrity across a wide frequency range. This stability is critical for RF and phased array antenna designs.

With a thermal conductivity of 0.64 W/mK and a low thermal coefficient of Dk (-58 ppm/°C), the PCB maintains electrical performance even under thermal stresses.

The CTE values (X/Y: 12 ppm/°C, Z: 45 ppm/°C) ensure excellent dimensional stability, reducing warping during thermal cycling and improving reliability in high-temperature aerospace environments.

A low moisture absorption rate of 0.08% protects the board from performance degradation in humid or moisture-prone environments.

Versatile Applications:

The F4BTMS450 PCB is specifically designed for high-performance and mission-critical applications such as:

Aerospace systems: Space equipment, cabin systems, and satellite communications.

Microwave and RF applications: Radar systems, feed networks, and phased array antennas.
