SpaceBridge XRF33F / XRF34F 3W & 4W Ka-Band Outdoor VSAT Transceiver

SpaceBridge XRF33F / XRF34F 3W & 4W Ka-Band Outdoor VSAT Transceiver 

The SpaceBridge XRF33F and XRF34F are integrated Ka-band outdoor VSAT transceivers offering 3 W and 4 W transmit power options for professional and consumer satellite broadband applications. Combining a transmit block upconverter (BUC), receive low-noise block downconverter (LNB), orthomode transducer (OMT) and field-configurable circular polarizer, the XRF provides a compact antenna feed solution. Its S-band transmit IF interface, 50 MHz reference compatibility and IP67 enclosure support outdoor broadband deployments.
