Frequently Asked Questions
Q: Does this Ku Band Block Up Converter (BUC) include an internal local oscillator (LO) and frequency conversion stage, or does it require external pumping?
A: Yes. The BUC includes an integrated local oscillator (LO) and internal mixer circuitry for frequency conversion. No external pumping signal or external frequency conversion equipment is required. The unit accepts an IF input signal in the 1000–2000 MHz range and internally up-converts it to the Ku-band RF output frequency range of 10.7–12.7 GHz through its built-in frequency conversion architecture.
For optimal frequency stability and phase noise performance, the BUC requires an external 10 MHz reference clock to be supplied via the IF input interface. This external reference is used to synchronize the internal local oscillator, ensuring accurate frequency generation and long-term stability for satellite uplink applications.
Key Points:
- Integrated local oscillator (LO)
- Built-in mixer and frequency conversion circuitry
- No external pumping signal required
- IF input: 1000–2000 MHz
- RF output: 10.7–12.7 GHz
- External 10 MHz reference clock required
- Suitable for VSAT, teleport, broadcast, and satellite ground station systems
This architecture simplifies system integration while providing the frequency accuracy and reliability required for professional satellite communication networks.
Q: The BUC specifications show an IF input frequency range of 1000–2000 MHz and an RF output frequency range of 10.7–12.7 GHz. If I input a 1000 MHz signal, it is converted to 10.7 GHz. If I input a 2000 MHz signal, how does the BUC achieve output frequencies up to 12.7 GHz? How is the frequency range switched?
A: The BUC achieves different RF output frequencies by adjusting its internal local oscillator (LO) frequency. The output frequency is generated through an internal frequency mixing process according to the following relationship:
RF Output Frequency = IF Input Frequency + Local Oscillator Frequency
The BUC contains an integrated synthesizer, local oscillator, and mixer circuit. By changing the LO frequency, the unit can translate the IF signal to different RF output frequencies across the Ku-band operating range.
Example 1
- IF Input: 1000 MHz
- Local Oscillator: 9.7 GHz
- RF Output: 10.7 GHz
Example 2
- IF Input: 2000 MHz
- Local Oscillator: 10.7 GHz
- RF Output: 12.7 GHz
Example 3
- IF Input: 1500 MHz
- Local Oscillator: 10.2 GHz
- RF Output: 11.7 GHz
The internal frequency synthesizer automatically generates the required LO frequency, enabling the BUC to cover the entire 10.7–12.7 GHz Ku-band output range without requiring external frequency conversion equipment.
