2017-05 Up/Downconverter, 950-1525 MHz, 140 MHz IF
The 2017-05 L-band Up/Downconverter converts 140 MHz to 950-1525 MHz (Up) and 950-1525 MHz to 140 MHz (Down) in 1 MHz
steps with low group delay and flat frequency response. Synthesized local oscillators (LO) provide frequency selection. 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 is manually controlled over
a -10 to +30 dB range for the upconverter and over a 0 to +50 dB range for the downconverter as adjusted by the front panel multifunction 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. LNB or SSPB +24 VDC and 10 MHz reference can be inserted on the RF lines as added options. A high stability
(±0.01ppm) option is also available. It is powered by a 100-240 ±10% VAC power supply & housed in a 1.75” X 19" X 16” 1RU chassis.
