Combiner & Multicoupler&Duplexer Integrated machine
The combiner Multicoupler&duplexer Integrated machine integrates the functions of combiner, Multicoupler and duplexer. It can not only reduce the number of equipment in the system, reduce the installation space of the cabinet, but also reduce the number of jumper connections to make the system cleaner. The system insertion loss is smaller than the vertical equipment, and the reliability is higher.

Product Description
Overview:
The combiner Multicoupler&duplexer Integrated machine integrates the functions of combiner, Multicoupler and duplexer. It can not only reduce the number of equipment in the system, reduce the installation space of the cabinet, but also reduce the number of jumper connections to make the system cleaner. The system insertion loss is smaller than the vertical equipment, and the reliability is higher.
Product Features:
- This combiner uses the 3dB bridge broadband combiner, which is not limited by the channel spacing. It can be widely used for combining in systems with relatively close channel spacing, and solves the problem of sharing antennas for combining near channel spacing.
- Equipped with radiator, can natural heat dissipation, high reliability.
- Each output port is equipped with an independent isolator to ensure the standing wave characteristics of each port, so that the isolation of each port is high and mutual interference is small.
- The signal compensation adopts the amplifier with excellent performance, low noise coefficient, good amplification effect, and effectively improves the influence of antenna feed on receiver sensitivity.
- The equipment gain can be adjusted according to the project site, and the dial adjustment is accurate and convenient.
- The equipment is equipped with high-power cavity duplexer, with small insertion loss, high system reliability and good out-of-band suppression.
- The equipment body is made of aluminum alloy materials, with solid structure and light weight. It can be installed on a series of 19-inch standard frame, which is beautiful and atmospheric.
