Indoor unit (IDU) realizes the mutual conversion between the service signal and IF analog signal. Two types of IDU are available:
IDU 610 is 1U high and supports one microwave direction.

IDU 620 is 2U high and supports maximum four microwave directions.

A global OEM/ODM supplier to core equipment vendors and digital microwave systems vendors, Comba provides high-performance, low-cost products and services, including the outdoor units (ODU), digital microwave antennas & couplers, and indoor units (IDU). ML-GS.jpg
Comba is the smart choice for companies seeking a premier original design manufacturing partner.  Clients can therefore reduce the expenses and time-to-market associated with new product development and launch through the outsourcing of design, development and manufacturing elements to Comba.  To date, thousands of Comba's OEM products have been deployed worldwide in wireless communication and broadband networks.

Cutting-edge R&D, Cost-Effective Manufacturing
Combining the best of both worlds with facilities on both sides of the Pacific Ocean:
  • Led by the main R&D center in Guangzhou (China), there are three more R&D laboratories located in Nanjing (China), California (USA) and the Wavelab R&D center in Virginia (USA)
  • Cost-effective manufacturing facilities in China with a production base occupying over 18,000 square meters.  Phase III of the production base will further expand capacity and will launch by end of 2009.
With this unbeatable combination, Comba offers high volume, reliable and competitively priced digital microwave equipment.
