Ku Band Offset Block Upconverter
Features
- L band input Ku 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 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 13.75 to 14.25 GHz
- IF input frequency range 950 to 1,450 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
- Higher output digital attenuator with up to 30db range
- Different nominal gains to suit specific applications
- Built in digital attenuator with up to 30db range
