The electronic up-converter module is then used to encode the electrical signal onto a radio frequency carrier of 220 GHz.
2 -- Powerstax, one of Europe's power solutions manufacturers, has launched the new Powerstax TVS1001, rugged up-converter designed for use in military tactical vehicle systems for operations in remote locations and non-tactical vehicle security systems.
Built on its flagship innovative product, the DVU5000, the new Universal Modulator, the DVU5000D, integrates a digital up-converter that improves substantially the performance of the modulator while increasing reliability.
A test example calculating total harmonic distortion using an SI waveform generator, an SI up-converter, an SI down-converter, an SI digitizer with IVI drivers, and several SI software components illustrates the interactions between the hardware and software as well as how to set it up and get the desired results.
The model 22TX0392 is a gallium arsenide (GaAs) monolithic microwave integrated circuit (MMIC) subharmonically pumped up-converter.
In a classic up-conversion scenario, the signals to be transmitted are sent to the first up-converter at 70 MHz which mixes the signal with another frequency, producing sum and difference versions of the original signal.
This signal is taken to an up-converter circuit, where it is mixed with a locally generated microwave carrier called the local oscillator (LO) signal (fo) in the microwave frequency range.
