What is consistent, however, is that
doublers are always free or cost very little.
For testing the large-signal performance of the two frequency
doublers, the bias voltages were set to [V.
Conversion loss for the
doublers is typically 15 dB at a drive level of +15 dBm.
The low noise front end without the frequency
doublers is shown in Figure 12.
The best operation for frequency
doublers is with a load resistance from 5 to 10 [omega] where circuit efficiency will be high and both power output and bandwidth will be of sufficient magnitude.
As a result, the focal point of this design effort was on the development of a high efficiency frequency
doubler using power FET devices.
It is an honor to include Faroudja's high-end line
doublers, their sophisticated quadruplers and high-end DVD players among our product offerings.
Many users have been pleasantly surprised to see that BARCO's Line
Doubler provides video image quality that is very comparable to that of `exotic' line
doublers costing many thousands of dollars more," commented Barlow.
544 Mbps, up to a distance of 10 miles with
doublers.
With the emergence of HDSL
doublers, service provider technicians are often required to test HDSL loops before the installation of the HDSL network equipment.
