Matrix Switching Systems   

 

CrossPoint Technologies' IF/RF Switch Matrix provides switching and distribution in a rack mount package. An input can be routed to one or all outputs simultaneously. The solid state GaAs switches have virtually unlimited life. The matrix provides unity gain (0 dB) as standard. Systems can be tailored to antenna switching applications, where low noise is most critical, or for IF switching applications where high intercept and high compression points are desired. LNB power insertion is also available.

The modular packaging permits the design of larger configurations using 16 x 16 building blocks. The larger matrices retain their full fan-out, non-blocking features. A centralized controller and power supply system reduce costs of  the larger matrices.

The standard Remote control interface is RS-232 and RS-422 (user selectable). Optional interfaces include Ethernet and IEEE-488. Custom interfaces can be provided, please consult the factory.

Optional Features for Switch Matrix Products

bullet

Redundant Power Supplies

Typical configurations are dual redundant supplies. Hot swap power supply drawers have fully independent AC paths. N+1 configurations are available for larger matrices.

bullet

Ethernet Remote Control

10 BASE-T RJ-45 interface available.

bullet

No Local Front Panel

The standard front panel can be deleted. The Matrix will be remotely controlled only.

bullet

75 Ohms

50 ohms is standard. Consult factory for other impedances also.

bullet

Manual Attenuator

An attenuator is available on the input of the matrix to accommodate excess LNA/LNB gain

bullet

Signal Presence Detectors

Fixed threshold detectors are available at the inputs and/or outputs. These detectors provide remote and local status indications for signal power level.
