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 high precision. Utilizing a high-Q air-cavity construction, this divider offers significantly better power handling and lower insertion loss compared to traditional microstrip designs. Optimized for the 698MHz to 2700MHz spectrum, it provides seamless coverage for all major cellular bands, including 700MHz LTE, 800/900MHz GSM, and 1800/2100/2600MHz high-band frequencies.
The divider features precision-machined N-Type Female connectors on all ports, ensuring a secure, low-loss, and high-reliability interface for critical infrastructure. Its robust internal architecture ensures excellent phase and amplitude balance across the four output ports, which is vital for maintaining signal uniformity in multi-antenna networks. Housed in a weather-resistant, passivated aluminum enclosure, it is engineered for long-term durability in both indoor head-ends and sheltered outdoor environments.
Key Technical Advantages
-
Broad Wideband Coverage: Covers the full 698-2700MHz range, making it a versatile solution for multi-carrier and multi-band cellular infrastructure.
