Ku-band DNC consists of an RF Section, a Local Oscillator and a DC/DC Converter.
RF Section converts the 14GHz input signals to the 12GHz signals using Local signal of 1248MHz(Type 1), 1748.5MHz(Type 2), 2289MHz(Type 3), 2789.5MHz(Type4), and 3,043MHz(Type 5).
Local Oscillator provides the Local signal to the Mixer of the RF Section. TCXO is used for Local signal reference source.
DC/DC Converter supplies the secondary voltage to the RF Section and the Local Oscillator. And it receives the Turn ON and OFF commands and provide the ON/OFF Status telemetry.
Typical performance of Ku-band DNC is as follows; Gain: 25dB nom. / NF: 18dB max. / IP3: +30.5dBm min. / Pdc: 8W max.
