LCS 6 Channel VRC-99B Tranceiver
4dB Noise Figure, 30W per channel
19 Lbs
The North Star Scientific (NSS) six channel transceiver
addresses the need of the U.S. Navy to send a high data rate
communications link (10Mb/s) to multiple mine hunter submarines.
The transceiver is fed from a single modified VRC-99B radio
(1 watt output power level), located in the radio room of the
Littoral Combat Ship (LCS). The NSS transceiver can be mounted in
the mast of the LCS ship, where approximately 150 foot of RF
cable and multiple 18 gauge wires connect the radio to the
transceiver and the power supply.

The transceiver connects to six separate antennas, providing a
communications link with a full 360° of coverage. Because of the
unique rake receiver used by the VRC-99B radio, every other
antenna channel on the receiver portion of the transceiver will
have a 50 to 70ns delay line. The NSS tranceiver features delayed
receiver outputs that allow the VRC-99B to treat the individual
signals as if they are multi-path and coherently add
them together to enhance the signal to noise ratio. Output power
for each of the six channels from the transceiver is 30+ watts.
All channels have VSWR protection and operate without
damage into a high VSWR load.
The LCS 6 Channel Tranceiver has the following technical characteristics:
