Key Performance Attributes Explained
Broadband Frequency Coverage for Flexibility
One of the standout features of this 2×2 Hybrid is its extensive frequency range, spanning from 698 MHz to 4000 MHz. This wide bandwidth covers key cellular bands including LTE, 5G NR, and various private network frequencies, making it a versatile solution for multi-band implementations. Whether you are upgrading an existing 4G network or deploying a new 5G infrastructure, this combiner adapts to your needs without requiring multiple components.
Excellent Signal Integrity and Low Loss
Signal loss is a critical factor in any RF design. With an insertion loss of 3 dB (with a tolerance of ±0.8 dB), this hybrid combiner ensures that the majority of the input power is efficiently transferred to the output ports. This level of loss is characteristic of a true 2×2 hybrid, which inherently splits power equally. The low VSWR of 1.3 indicates excellent impedance matching, minimizing reflections and optimizing power transfer to the transmission line.
Superior Isolation and Intermodulation Performance
Isolation of greater than 20 dB between the input ports ensures that signals do not interfere with each other, preventing cross-talk and maintaining signal purity. Furthermore, intermodulation distortion is kept to an impressively low level of -155 dBc when tested with two +43 dBm carriers. This is especially important in high-power environments where intermodulation products can degrade system performance or interfere with adjacent channels.
Built for Harsh Environments
With an IP65 ingress protection rating, this 2×2 Hybrid is designed to withstand dust ingress and water jets from any direction. The operating temperature range of -30°C to +70°C, combined with the ability to handle up to 95% relative humidity, ensures reliable operation in outdoor or industrial settings where weather conditions are unpredictable. The robust 4.3-10 female connectors are widely recognized for their low PIM characteristics and ease of installation.
Conclusion
When selecting a combiner for your next RF project, the MOP-HC-738-300-2:2MF offers a compelling balance of performance, durability, and value. Its broad frequency coverage, high isolation, low intermodulation, and rugged IP65-rated enclosure make it an ideal choice for demanding cellular and wireless applications. Whether you are a system integrator, network engineer, or infrastructure manager, this 2×2 Hybrid provides the reliability and efficiency needed to keep your network running smoothly. Invest in a component that delivers consistent results across diverse conditions, and ensure your deployment meets the highest standards of signal integrity and operational uptime.
