series upconverters cover the frequency range of 18 to 110 GHz in seven
waveguide bands. These upconverters have a balanced mixer configuration for high LO to RF
isolation. They are constructed with a rugged, split-block mechanical design that utilizes
GaAs beam-lead Schottky barrier diodes.
The
upconverter combines LO and IF signals and produces RF output signals at frequencies of
their sum and difference, i.e., LO ± IF. |
An
optional integral waveguide filter is available to produce a single-sideband output
signal. Typical IF bandwidth is a few GHz, but wider bandwidth upconverters are available.
Local oscillator waveguide port
may be in either the same waveguide band as RF waveguide port, or in a lower or higher
waveguide band (the two adjacent bands), depending on LO frequency. The upconverter can
supply several milliwatts of single-sideband output power with the proper input power
levels. |
