Product Overview
The MHC-327-44-4F-160 is a high-performance 380-2700MHz 4x4 Hybrid Coupler (Matrix) engineered for sophisticated signal combining in multi-band networks. Perfectly suited for TETRA systems, 4G/LTE, and high-capacity In-building Solutions (IBS), this coupler allows for the combining of up to four inputs into four outputs with minimum interference. Featuring an ultra-low PIM of ≤-160dBc and a massive power handling capacity of 300W per port, it ensures clean, reliable signal distribution. Its IP65-rated enclosure and 4.3-10 Female connectors make it a top-tier choice for both indoor Distributed Antenna Systems (DAS) and rugged outdoor base station environments.

Frequently Asked Questions
- Q1: What is the primary function of a 4x4 Hybrid Coupler in a multi-operator network?
- A: A 4x4 Hybrid Coupler is used to combine up to four different signal sources (such as different mobile operators or frequency bands) and distribute them across four output ports. This allows for efficient resource sharing in antenna systems without significant interference between the sources.
- Q2: Why is the -160dBc PIM rating critical for TETRA and LTE systems?
- A: Passive Intermodulation (PIM) can cause interference that degrades call quality and data speeds. A rating of ≤ -160dBc ensures that the coupler remains "quiet" even under high power, maintaining the signal integrity required for mission-critical TETRA and high-speed LTE networks.
- Q3: Does the IP65 rating make this coupler suitable for extreme outdoor weather?
- A: Yes, the IP65 rating indicates that the coupler is dust-tight and protected against water jets from any direction. This makes it highly reliable for outdoor base station installations where it might be exposed to rain and dust.
- Q4: How does 300W average power handling benefit large-scale IBS projects?
- A: With 300 Watts of power handling per port, this coupler can safely manage high-power signals from multiple base stations simultaneously. This high overhead prevents thermal damage and ensures stable performance in large-scale Distributed Antenna Systems (DAS).
