30mil RO4534 PCB 2 Layer Immersion Silver RF Circuits

We are excited to introduce our newly shipped PCB utilizing RO4534 substrates, meticulously crafted to meet the stringent demands of the antenna market. Developed by Rogers Corporation, RO4534 laminates build upon the success of the RO4000 series, extending its capabilities into mobile infrastructure applications. This ceramic-filled, glass-reinforced hydrocarbon material delivers controlled dielectric constants, low loss performance, and excellent passive intermodulation (PIM) response, making it an ideal choice for microstrip antenna applications.

Key Features
- Dielectric Constant: 3.4 at 10 GHz
- Dissipation Factor: 0.0027 at 10 GHz
- PIM Value: Typical -157 dBC
- Thermal Coefficient of Expansion (CTE)**:
- X axis: 11 ppm/°C
- Y axis: 14 ppm/°C
- Z axis: 46 ppm/°C
- Glass Transition Temperature (Tg): >280 °C
- Moisture Absorption: 0.06%
- Lead-Free Process Compatibility: Yes

Benefits:
- Low Loss, Low Dk and low PIM response for wide range of application use
- Thermoset resin system compatible with standard PCB fabrication
- Excellent dimensional stability for greater yield on larger panels sizes
- Uniform mechanical properties for maintaining mechanical form during handling
- High thermal conductivity for improved power handling
- CTE similar to that of copper, reducing stress in PCB antenna
