4. UPC-590L-M Up-Converter Description 

 

Block diagram 

The UPC-590L-M up-converter consists of two identical assemblies that share a common local oscillator. The 

following describes one of the assemblies. The RF input is first applied to a 5 to 85 MHz bandpass filter and then 

to the double-balanced mixer. A 200 MHz local oscillator is mixed with the filtered RF input to provide an IF 

output range of 205 to 285 MHz. The mixer conversion loss is approximately 8 dB. The mixer IF output is applied 

to a 20 dB attenuator and lowpass filter with a corner frequency of 320 MHz. The lowpass filter reduces the 2

nd

 

and higher harmonics of the oscillator leakage through the mixer. A power supply printed circuit board (model 

CPS-3) uses a linear low noise, low dropout voltage regulator to provide regulated 5.0 Vdc to the oscillator.
