Comtech LBC-4000 L Band / IF (70/140MHz) Up/Down Converter

Description

The Comtech LBC-4000 L Band / IF (70/140MHz) Up/Down Converter System is an L-Band to IF 70 MHz (140 MHz optional) frequency converter. The Comtech LBC-4000 L Band / IF (70/140MHz) Up/Down Converter is packaged in a 1RU 19-inch chassis with two front panel accessible up converter or down converter modules. It contains two diode “OR-ed” internal power supplies for increased reliability and microprocessor-based Monitor & Control (M&C) functions.

An optional version is offered that eliminates the drop front panel and support for a second converter module. Instead, it supports a single converter module and provides front panel mounted, 20 dBc nominal, sample ports (SMA for L-Band, BNC for IF). The Comtech LBC-4000 up converter module translates a 70 MHz IF input signal (140 MHz optional) up to a user-selected frequency at L-Band (950 to 2000 MHz, 950 to 2150 MHz optional). The L-Band output can drive the input of the Comtech MBT-4000 block up converter or other RF equipment with an L-Band input.

The Comtech LBC-4000 down converter module translates an L-Band (950 to 2000 MHz, 950 to 2150 MHz optional) IF input signal down to a user selected frequency in the 70 MHz (140 MHz optional) IF band. The Comtech LBC-4000 can be locked to an internal reference or an external 5 or 10 MHz reference signal. The Comtech LBC-4000 is an excellent choice for interfacing legacy 70 or 140 MHz equipment to quad-band or tri-band block converters.
