Advantages

• Low loss: The RO4350B has a Dk of 3.48 and a Df of 0.0037 (10 GHz), with a loss of only 0.15 dB/inch at 20 GHz.

• Dk stability: The dielectric constant tolerance is controlled within ±0.05, and the temperature coefficient is as low as -0.04%/°C.
  
• High-frequency compatibility: Supports millimeter-wave frequency bands (e.g., the RO3003 has a Dk of 3.00 at 77 GHz), making it suitable for applications such as 5G and radar.
  
  
  

Applications

• 1. Communications
  

  5G base stations: Used in core components such as antenna elements, power amplifiers (PAs), and low-noise amplifiers (LNAs), supporting 5G high-frequency band (Sub-6GHz, millimeter wave) signal transmission.

  Wireless communications equipment: RF front-end circuits in Wi-Fi 6/7 routers, satellite communication terminals, and radio frequency identification (RFID) readers.

  Fiber optic communications: Adapts to high-speed digital signal processing circuits in optical modules to meet the transmission requirements of 100G/400G optical communications.

• 2. Aerospace and defense
  
  Airborne radar: Used in high-frequency circuits in radar transceiver modules (T/R modules), withstanding extreme environments such as high altitude, high temperatures, and vibration.
  Satellite communications: Adapts to RF components in satellite payloads to ensure stable signal transmission in space.
  Electronic countermeasures equipment: Used in high-frequency signal transmission and reception circuits, requiring low loss to ensure signal accuracy.
• 3. Industrial and medical
  
  Industrial microwave equipment: Control circuits for microwave sensors and industrial heating equipment rely on stable dielectric properties for precise control. 
  Medical equipment: such as radio frequency coils for magnetic resonance imaging (MRI) equipment and signal processing modules for ultrasonic diagnostic equipment, taking into account both high-frequency performance and reliability.
