Description
The 4-Way Microstrip Type Power Divider is a high-performance passive component designed to split an input RF signal into four equal-amplitude, in-phase output signals. Utilizing a Wilkinson microstrip design, this divider provides excellent port-to-port isolation and impedance matching in a significantly smaller form factor than cavity-type equivalents. Optimized for the 698MHz to 2700MHz spectrum, it provides full coverage for all major cellular bands including LTE, GSM, and DCS, as well as 2.4GHz WiFi frequencies.
The divider features precision-machined SMA-Female connectors on all ports, ensuring a secure and low-loss connection suitable for high-density microwave assemblies. The internal circuit is etched on high-frequency, low-loss dielectric substrates, providing a flat frequency response and consistent performance across the entire operating band. Housed in a compact aluminum enclosure, it offers superior RF shielding and is ideal for space-constrained applications in both commercial and military electronic systems.
Key Technical Advantages
-
Ultra-Compact Form Factor: The microstrip design allows for a lightweight and small footprint, making it ideal for integration into portable devices or tight equipment racks.
-
Broad Wideband Coverage: Covers the full 698-2700MHz range, supporting multi-service signal distribution across cellular and wireless data bands.
-
Excellent Port-to-Port Isolation: Internal balancing resistors provide high isolation between output ports, preventing signal cross-talk and protecting upstream sources.
-
Superior Phase and Amplitude Balance: Precision manufacturing ensures that the four output signals remain highly symmetrical, which is critical for MIMO and phased-array applications.
-
Rugged Shielded Construction: The aluminum housing provides excellent electromagnetic interference (EMI) protection and mechanical durability.
