MODEL 2016-05A Downconverter
1.0 General
1.1 Equipment Description
2016-05A L-Band Downconverter converts 950 to 1525 MHz to 140 MHz in 1 MHz steps with low group
delay and flat frequency response. The 2016-05A Input and Output levels have been optimized to support
transmit from an L-band modem to a 140 MHz IF upconverter. Multi-function push button switches select the
RF frequency, gain, and other parameters. Front panel LEDs provide indication of DC power (green), PLL
alarm (red), and remote operation (yellow). The gain is adjustable from 0 to +50 dB. Remote operation allows
selection of frequency and gain. Parameter selection and frequency and gain settings appear on the LCD
display. Standard connectors are BNC female for IF output and the optional external reference input and
reference output, and Type F female for the RF input. A high stability (±0.01ppm) reference, LNB +24 VDC,
0.4 Amps power and 10 MHz reference (includes a 10 MHz output connector), are available Options. The unit
is powered by a 100-240 ±10% VAC power supply, and housed in a 1.75” X 19” X 16” 1RU chassis.
