L-band Matrix 128 x 128 Model NGM-21-xx

128 Inputs x 128 Outputs Distributive Hot-swap NiGMa L-band Matrix.

The NiGMa L-band Switch Matrix / L-band Router is housed in a 6U 19" rack enclosure and has a module capacity of 32 inputs x 32 outputs. It can be part populated to any size, and can then be hot expanded up to 32 x 32. The NiGMa L-band Router can also be easily formed into larger Matrix Systems up to 512x512 by adding additional modules.

Now in its 3rd generation, the NiGMa L-band Matrix has proved to have genuinely high performance with excellent flatness or frequency response, excellent isolation, and linearity - a truly leading edge L-band Router.

A variety of impedances and connector types are available, as shown below.

The NiGMa L-band matrix has hot swap of all active components - RF cards, VGA human interface, CPU's and PSU's.

In addition the NiGMa L-band Matrix has the designed-in resilience provided by one RF card for each RF input and output, dual redundant CPU's, and dual redundant PSU's.

The NiGMa L-band Matrix also has extensive on-board monitoring - and reporting - of RF card amplifier status, CPU and PSU status and HMI communications.

Control of the RF Matrix can be done locally via the touchscreen and VGA display, and remote connection is via RS232/485 serial and RJ45 Ethernet ports.

Web Browser Interface is provided as standard with the NiGMa L-band Switch Matrix.

The NiGMa Switch Matrix is available in a variety of frequency ranges covering IF, UHF/VHF and L-band. They are generally used for satellite communications applications in teleports, and ground stations.

The NiGMa L-band Switch Matrix is available as a fan-out or distributive Switch Matrix, for receive or downlink applications; and as a fan-in or combining Switch Matrix for transmit or uplink applications. The L-band matrix is used to provide flexibility in the routing of antennas to receivers or modems; to allow remote routing of satellite signals to receivers or modems; and to help optimise the use of receiving capacity. The NiGMa L-band Switch matrix reduces the overall cost of an earth station by optimising capacity, and allowing remote control - this helps both capex and opex expenses.

The NiGMa L-band Switch matrix can also be incorporated into an overall automatic redundancy Network Management System to enhance the resilience of the overall earth station equipment. The NiGMa Switch Matrix is a high resilience module with hot swap of all active components, and dual redundant PSU's and CPU's.

Non-blocking: this means any input can be routed to any output.

In general our solid state (L-band) matrices are non-blocking.

Full Fan-out Matrix (or fully distributive or splitting matrix): any input can be routed to any output. One input can be routed to many outputs. Each output can only have one input. Tends to be more RX.

Up to 32 inputs x 32 outputs we would recommend the NiGMa matrix which has a full capacity of 32 inputs x 32 outputs, but can be supplied part-populated, and expanded in single increments. Multiple modules can be joined together to make systems such as 32 inputs x 16 outputs.

Up to 64 inputs x 64 outputs we would recommend the Vortex matrix which has a full capacity of 64 inputs x 64 outputs, but can be populated in increments of 16.

Up to 128 inputs x 128 outputs we would recommend the Vulcan matrix which has a full capacity of 128 inputs x 128 outputs, but can be populated in increments of 8.
