TC350 PCB is crafted from Rogers TC350 laminates, featuring a unique composition of PTFE, highly thermally conductive ceramic fillers, and woven glass reinforcement. This combination results in low insertion loss and high thermal conductivity, making the TC350 an excellent choice for high-power applications. Its design ensures superior reliability and reduced operating temperatures, ideal for power amplifier and antenna systems.

With a dielectric constant (Dk) of 3.5 at 1 MHz, 1.8 GHz, and 10 GHz, the TC350 laminates maintain excellent stability across various temperatures. This stability is crucial for maximizing gain and minimizing bandwidth loss in power amplifiers and antennas. Moreover, it is key for phase and impedance-sensitive devices, such as network transformers and Wilkinson Power Dividers.

Key features include:
- Dissipation Factor: 0.0015 at 1 MHz, 0.0018 at 1.8 GHz, and 0.002 at 10 GHz
- Coefficient of Thermal Expansion (CTE): 7 ppm/°C in the x and y axes, 23 ppm/°C in the z-axis from 50°C to 150°C
- Low Thermal Coefficient of Dk: -9 ppm/°C from -40°C to 140°C
- High Thermal Conductivity: 0.72 W/mk
- Moisture Absorption: 0.05%
- T260, T288, T300: > 60 minutes

TC350 PCB benefits from reduced junction temperatures and improved reliability, with excellent heat dissipation and management. This leads to enhanced bandwidth utilization and efficiency for amplifiers and antennas, along with superior plated-through hole reliability.

Constructed as a 2-layer rigid PCB, it features 35 μm of copper on both layers and a core thickness of 0.254 mm (10 mil) of TC350. The board dimensions measure 97.5 mm x 31.7 mm (± 0.15 mm) with a finished thickness of 0.37 mm. It supports minimum trace and space requirements of 5/5 mils and a minimum hole size of 0.2 mm, with no blind vias. The immersion gold surface finish (ENEPIG) enhances solderability.

This PCB is supplied with artwork in the Gerber RS-274-X format and meets the IPC-Class-2 quality standard. It is available for worldwide, making it accessible to engineers globally.

Typical applications include power amplifiers, filters, tower-mounted amplifiers (TMA), tower-mounted boosters (TMB), thermally cycled antennas sensitive to dielectric drift, and microwave combiners and power dividers. With its advanced thermal management and excellent electrical performance, the TC350 PCB is a reliable choice for modern electronic designs.
