2015-140 Upconverter, 13.75 - 14.75 GHz

The 2015-140 Upconverter converts 70 ± 18 MHz to 13.75 to 14.75 GHz in 125 kHz steps with low group delay and flat frequency response. Synthesized local oscillators (LO) provide very low phase noise, ± 0.01 ppm stability frequency selection. Push button switches select the RF frequency, gain, and other parameters. Front panel LEDs provide indication of PLL alarm (red), Remote operation (yellow) or the TX carrier is Muted (yellow). Variable attenuators for the IF input and RF output provide a gain range of 0 to +30 dB as adjusted by the front panel pushbutton switches. Remote operation allows selection of frequency and gain. Parameter selection and frequency and gain settings appear on the LCD display. Connectors are BNC female for IF and external reference input and SMA female for the RF output. Powered by a 90-260 VAC power supply; 1 3/4” X 19 “ X 16” rack mount chassis.
