Test Loop Translators from Atlantic Microwave simulate the satellite transponder frequency conversion for system alignment and continuous quality monitoring.
Previously, frequency conversion in the power supply at Portsmouth was carried out by rotary frequency converters (RFCs) - complex mechanical systems that combine motors, generators, drives and ancillary regulation and control equipment.
There are two small lasers to fix the frequency of the emitted pulses, a laser oscillator to generate pulses, two amplifier stages that boost the energy of the light pulses to the required value, and a frequency conversion crystals stage to produce the correct wavelength.
Both the MxL3710 and MxL3711 utilize MaxLinear's patented Full-Spectrum Capture(TM) (FSC(TM)) technology that can simultaneously digitize up to 1.4GHz of spectrum, eliminating any discrete components usually required for frequency conversion. The MxL3710 and MxL3711 differ in their supported output interfaces with MxL3710 featuring two SGMII high-speed interfaces while MxL3711 supports one SGMII and one PCIe.
The company offers RF detection, frequency conversion, broadband amplification, power management, and repair/re-engineering of subsystems for obsolescence mitigation and extending system lifetime.
Using a novel technique of fabricating designed nano-crystals embedded in a transparent polymer and placed on a glass substrate, the ANU team demonstrated non-linear frequency conversion six orders of magnitude higher than before.
Furthermore, the system offers high-pressure air blower with independent and changeable frequency conversion controls and with special design of flue and blast pipe, which guarantees the negative pressure in the tail stock.
RF ICs are mainly used in devices that perform the functions such as amplification, frequency conversion, and signal filtering.
As a recognized leader in RF products, Comtech EF Data offers an extensive product line of frequency conversion and amplifier solutions for indoor and outdoor environments.
It utilizes coherent frequency conversion to efficiently generate either single photons or pairs of single photons when excited with a laser that operates at a different wavelength.
This wide range frequency conversion phenomenon can easily be adopted for controlling of variable frequency drives.
