High power block upconverter

A system and method for high power block upconversion having a stand-alone and surface-mountable component is provided. The HP-BUC system of the invention provides a "drop-in" component capable of mixing a local oscillator signal with an IF signal to produce an RF signal in the millimeter-wave and higher bands. In addition, the HP-BUC provides filtering of unwanted spurious signals and requires no further signal amplification prior to transmission, for example in a satellite communications system. |

DETAILED DESCRIPTION The subject matter of the present invention is particularly suited for use in connection with a satellite ground terminal in a communication system, and more particularly in connection with frequencies in the millimeter-wave and higher bands.
As a result, the preferred exemplary embodiment of the present invention is described in that context.
It should be recognized, however, that such description is not intended as a limitation on the use or applicability of the present invention, but is instead provided merely to enable a full and complete description of a preferred embodiment.
Generally, a high power block upconverter (HP-BUC) system according to various aspects of the invention provides a surface-mountable component for mixing a subharmonic local oscillator (LO) signal with an intermediate frequency (IF) signal to produce a radio frequency (RF) signal, in particular, an RF signal at millimeter wave bands.
The HP-BUC system is particularly suited for K band satellite transceiver communications; however, it should be appreciated that the present invention has applicability to other frequency bands.
In addition, a HP-BUC system according to various aspects of the invention provides filtering of unwanted spurious signals resulting from the mixer and RF signal power amplification.
Moreover, a HP-BUC system of the invention provides a reduced cost "drop-in" component.
The complexity of the present system is reduced by optimally separating high frequency "chip and wire" assembly from low cost surface mount technology.
Yield is improved due to a higher percentage of the system being assembled using robust surface mount technology.
FIG.
1 illustrates a satellite ground terminal system 100 according to one embodiment and one application of the present invention.
System 100 includes an IF multiplexer 102, an HP-BUC 104 in accordance with the present invention, an RF multiplexer 106, a low noise block downconverter (LNB) 108, an antenna 110, and a cable 112.
IF multiplexer 102 combines an IF input signal and an IF output signal (typically the signals are at different frequencies) onto a single cable
