Comtech EF Data XSAT-7080 X-Band TDMA VSAT Transceiver
XSAT 7080 offers a 5 W, 10 W, 25 W, 50 W, and 100 Wt transceivers
XSAT-7080 X-Band TDMA VSAT Transceiver
The Comtech XSAT-7080 X-Band Transceiver design utilized a talented team of RF engineers with many years of experience in designing and manufacturing satellite transceivers and other RF products. The XSAT-7080 family of 5 to 25 W, 50 W, and 100 W units is designed to provide the user with superior performance, long-term reliability and ease of installation with a very price competitive product. The XSAT-7080 is the perfect choice for your VSAT application for TDMA, DAMA, and SCPC/MCPC sites requiring higher power.
Full Rated X-Band Power
The XSAT-7080 delivers the full rated power, or more, measured at the 1 dB compression point and at the output flange. The user realizes the useable output power that is available and receives full value for the investment.
Phase Noise
The dual synthesizers in the XSAT-7080 deliver superior phase noise performance, exceeding Intelsat specifications by a very comfortable margin. The user receives the benefits of spectral purity and the ability to go into multi-carrier environments with less concern.
Third Order Intercept (TOI)
The design of the XSAT-7080 gives the user a high TOI that allows multi-carrier applications without the concerns normally associated with low power environments. The XSAT-7080 delivers performance usually found only in SSPA systems.
Small, Compact Design
The XSAT-7080 offers a 5 W, 10 W, 25 W, 50 W, and 100 Wt transceivers. This design allows quick, easy installation for these higherpowered transceivers. With the use of the EDMAC features of the companion CDM family of modems, even installation can be made without the requirement for expensive, heavy test equipment.
Full Monitor and Control (M&C)
Designed into the XSAT-7080 are a variety of methods to monitor and control this device. The XSAT-7080 offers full Monitor and Control from a small, convenient Hand-Held Terminal or easy access via RS-232 or RS-485 connections. Full remote M&C can be achieved through the companion CDM Modem family or the PC Windows-based EDMAC proprietary monitor and control software.
Redundancy
The XSAT 7080 is available in a 1:1 redundant configuration.
