Wavestream Gilat 757C Powerstream Series C-Band Satcom SSPAs
Transmit Frequency 5.85 - 6.425 GHz, IF Frequency 950-1525 MHz (with BUC option), Frequency Reference (10 MHz on IF) 0 dB ± 5 dB
757C 600 Watt C-Band Amplifier
** This amplifier has reached end of life. Please contact Digisat for a suitable replacement. **
The Wavestream Gilat new PowerStream 757C Solid State Power Amplifier (SSPA) provides high output power in a compact rack-mount unit to support broadcast satellite communications systems worldwide. The PowerStream 757C is suitable for mobile and fixed satellite communications where space is limited and greater efficiency is essential.
This high power amplifier is available in two configurations:
Indoor - 757C-i
Outdoor - 757C-o
Easy Installation
Designed as a plug and play TWTA replacement to facilitate system upgrades, the PowerStream 757C incorporates Wavestream’s proven, next generation Spatial Power Advantage technology to provide high output power and lower power draw. For system integrators looking to implement new technology while lowering operating costs, the PowerStream 757C offers improved reliability and significantly reduced energy costs over the lifecycle of the system.
Amplifier Control
The PowerStream 757C-i provides an easy-to-view front panel display screen and quick-touch function keys for convenient access to a variety of system status data, including power, temperature, fault, and local/remote information.
Optional 1:1 Redundancy Kits are available to provide an integrated solution for uninterrupted, reliable broadcast satellite transmissions. The 1:1 Redundancy Kit integrates the waveguide, switch and mounting hardware, and offers ease of installation and subsequent maintenance to accommodate standard 19” rack cabinets.
