Description
This balanced FM combiner employing broadband hybrids and FM tunable filters enable the combining of FM transmitters up to 118 kW with a total output power of up to 180 kW. If you have demands on low losses with close frequency allocation this is the right product.
Product Features:
- Flexible modular design
- Low insertion loss
- Retunable
- 700kHz channel spacing
Data in tables is typical. The combiner can be tuned for other specifications or bandwidths, please contact us for a specification designed for your requirements. All average power values and technical data refer to an ambient temperature of + 20-25 °C with normal air flow. The product will have a maximum surface temperature of + 70 °C. Maximum power capacity may be lower depending on channel allocation.
