Ka-band Block Up and Down Converters
Rack-mount configuration
Features
- Ultra-stable, ultra low noise Lucix Internally-Referenced Dielectric Resonator Oscillator LOs
- Best-in-Class Phase Noise performance
- Low EMI, light weight aluminum chassis with EMI–sealed cover
- Automatic Internal/External Reference selection
- Upconverter RF Mute on Command or by Alarm
- RF and LO monitor ports
- 19” Rack Mount or Integrated Single Module physical configurations
This family of Converters is ideal for satellite communication system applications. These designs combine Lucix experience in Satellite Telecommunications System Engineering with expertise in ultra-stable, low phase noise Dielectric Resonator Oscillators (DROs), low noise amplifiers (LNAs), frequency converter modules, and high Q filters, to produce a best-in-class, feature-rich frequency converter. The main microwave internal modules are all designed and manufactured by Lucix, and reflect aluminum-packaged hermetic hybrid MIC assembly technology for added reliability and high performance. These slim, all welded 19” rack assemblies provide L-band to Ka-Band translation and feature an extensive array of standard monitor/control features including a Summary Alarm with automatic RF output muting, external RF muting, compatibility with either 5 or 10 MHz external references, and a built-in ultra-stable DRO/LO reference. These converters can also be scaled to other RF frequency bands as high as 45 GHz.
