UPC-590L-M Up-Converter Installation and Operation 

See last page for copyright and document information, File: Reeve_UPC590_Instructions.docx, Page 1 

1. Description 

 

The model UPC-590L-M consists of two identical heterodyne converters with 5 to 85 MHz RF input and 205 to 

285 MHz IF output. It is designed for use with the Long Wavelength Array (LWA) Antenna and includes 15 dB of 

attenuation in each IF output path. The UPC-590L-M has the same dimensions and form factor as the LWA 

Power Coupler and Callisto instruments. Because the LWA Antenna has built-in front-end electronics with low 

noise figure and high gain, the UPC-590L-M has no RF input preamplification.  

 

The UPC-590L-M panel layouts are shown below. The front panel (left) has connectors for power (2.1 x 5.5 mm 

coaxial jack, center positive), a power switch and power indicator and two output connectors for the IF to the 

receivers (type N-female). The rear panel (right) has two input connectors for the RF from the LWA Power 

Coupler (type N-female). 

 

 

 

The basic configuration is shown below. The Converter is inserted between the LWA Power Coupler and the 

Callistos instrument or other receivers.
