Manufacturer profiles associated with Satellite Transponder.
Manufacturer listings support early research and capability understanding. They are not certification, ranking, or transaction guarantees.
A practical evidence checklist for RFQ preparation and supplier evaluation.
CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
According to the directory data, the receive frequency range is 10.7–12.75 GHz (Ku-band downlink) and the transmit frequency range is 14.0–14.5 GHz (Ku-band uplink), but other bands are available. Always confirm the exact frequency plan for your specific model.
The transponder uses gallium arsenide (GaAs) semiconductors, silicon germanium (SiGe) components, an aluminum housing, gold-plated connectors, and ceramic substrates. These materials are typical for space-grade electronics.
The operating temperature range is -40 to +85 °C, as listed in the directory. This is suitable for the space environment, but you should verify the thermal requirements for your specific mission.
Power consumption ranges from 50 to 300 W, depending on output power. The input power is 28 V DC ±10%. Confirm the actual power budget with the manufacturer for your application.
