2017-04A Up/Downconverter, 950 - 2150 MHz
The 2017-04A L-band Up/Downconverter converts 140 MHz to 950-2150 MHz (Up) and 950-2150 MHz to 140 MHz (Down) in 1 MHz
steps with low group delay and flat frequency response. The 2017-04A has lower RF level out of the upconverter and higher RF level
into the downconverter than the 2017-04 and is typically used to interface an L-band modem to a 140 MHz IF upconverter and
downconverter. Multi-function push button switches select the RF frequency, gain, and other parameters. Front panel LEDs provide
indication of DC power (green), PLL alarm for up and downconverters (red), remote operation (yellow), and Upconverter mute (yellow).
Gain can be manually adjusted over a -25 to +15 dB range for the upconverter and over a 0 to +50 dB range for the downconverter by
the front panel multi-function push-button 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 the optional external reference input
and output, and Type F female for RF. A high stability (±0.01ppm) option is also available. It is powered by a 100-240 ± 10% VAC
power supply and housed in a 1.75” X 19“ X 16” 1RU chassis.
