4. Introduction to Rogers RO4350B Base Material
Rogers RO4350B is a proprietary high-performance material engineered to bridge the gap between premium PTFE-based RF laminates and cost-effective epoxy/glass boards. It is a woven glass-reinforced hydrocarbon/ceramic composite that delivers electrical performance comparable to PTFE/woven glass (low loss, stable dielectric constant) while maintaining the manufacturability of standard epoxy/glass laminates.
A key advantage of RO4350B is its cost efficiency—it is available at a fraction of the cost of conventional microwave laminates. Unlike PTFE-based materials, it does not require special through-hole treatments or delicate handling procedures, simplifying manufacturing and reducing production costs. Additionally, it holds a UL 94 V-0 flammability rating, making it suitable for active RF devices and high-power RF designs where safety is critical.
5. Key Features of RO4350B Material
| Property | Value | Significance |
| Dielectric Constant (Dk) | 3.48 ± 0.05 (10GHz/23°C) | Consistent RF signal propagation; critical for antenna and amplifier designs |
| Dissipation Factor | 0.0037 (10GHz/23°C) | Low signal loss; preserves RF signal strength in high-frequency paths |
| Thermal Coefficient of Dk | +50 ppm/°C (-50°C to 150°C) | Stable Dk across temperature ranges; ideal for automotive/outdoor use |
| Thermal Conductivity | 0.69 W/m/°K | Efficient heat management; protects RF components from overheating |
| CTE (X/Y/Z axes) | 10/12/32 ppm/°C | Low in-plane expansion matches copper; reduces thermal stress |
| Glass Transition Temperature (Tg) | >280°C | High thermal stability; supports lead-free soldering |
| Water Absorption | 0.06% | Minimal moisture impact; stable performance in humid environments |
| Flammability | UL 94 V-0 | Fire safety compliance for enclosed electronic systems |
6. Typical Applications
Leveraging the performance and cost benefits of Rogers RO4350B, this 2-layer RF PCB is well-suited for the following applications:
-Cellular Infrastructure: Cellular base station antennas and power amplifiers (reliable RF performance for long-range signal transmission)
-RF Identification (RFID): RFID tags (low loss and compact design support efficient tag communication)
-Automotive Electronics: Automotive radar and sensors (temperature stability and durability meet automotive environmental demands)
-Satellite Communications: Low Noise Blocks (LNBs) for direct broadcast satellites (stable Dk and low loss ensure clear satellite signal reception)
