C Band Block Upconverter
Features
- L band input C band output
- Integrates with both solid state and travelling wave tube amplifiers (TWTAs).
- Small size, light weight and low power consumption enables simple installation inside TWTAs to produce a high power C Band BUC subassembly.
- The L band input can be supplied by any L band modem or exciter. This greatly simplifies installation design allowing the TWTA to be placed close to the antenna feed to minimise losses allowing the modems can be placed conveniently inside a cabin or shelter.
- RF output frequency range 5.850 to 6.425 GHz
- IF input frequency range 950 to 1525 MHz
- External 10 MHz Reference for station synchronisation multiplexed on L band IF input
- Out of lock alarm indicator
Options
- Auto switching internal OCXO reference to increase flexibility.
- Custom package outline for special applications
- Positive gain slope to compensate for frequency roll off
- Different nominal gains to suit specific applications
- Higher output powers for demanding applications
- Built in digital attenuator with up to 30 dB range
