Description
The 4-Way Cavity Type Power Divider is a high-capacity passive component designed to split an input RF signal into four equal-power output signals with minimal loss. Utilizing a high-Q air-cavity construction, this divider provides superior power handling and lower insertion loss compared to standard microstrip splitters. Optimized for the 300MHz to 1000MHz spectrum, it provides seamless coverage for UHF bands, TETRA, and low-band cellular frequencies, including the 700/800/900MHz bands.
The divider features precision-machined N-Type Female connectors on all ports, ensuring a secure, low-loss, and reliable interface for telecommunications infrastructure. Its robust internal architecture ensures excellent phase and amplitude balance across the four output ports, which is essential for maintaining signal uniformity in multi-antenna configurations. Housed in a weather-resistant, passivated aluminum enclosure, it is engineered for long-term durability in both indoor equipment rooms and sheltered outdoor environments.
Key Technical Advantages
-
Low Insertion Loss: The air-dielectric cavity design ensures maximum signal transmission efficiency, delivering high-intensity signals across all four output ports.
-
