Paradise Datacom’s IF to L-Band Up/Down Converter (IBC) is a self-contained (1RU) indoor
chassis which can be configured as a single thread system or as a 1:1 Redundant System.
The frequency agile Upconverter translates an IF (70 MHz)
frequency input signal to an L-Band frequency between 950
and 2050 MHz.
The frequency agile Downconverter translates a L-Band input
signal between 950 and 2050 MHz to an IF frequency of 70
MHz.
The IBC is designed specifically as the perfect frequency
interface that would transition a 70MHz base-band modem
output to an L-Band frequency for a block converter. The IBC
has two hot-swappable modules which can be removed without
interrupting the chassis power. The IBC can also be configured
with one up and one down converter module, two up converter
modules or two down converter modules. The redundancy
option can be utilized when configured with like converter
modules.
System control is available through the front panel and via rear
panel parallel I/O remote or serial I/O remote connectors.
