7703PA, 7703PA-LNB, 7703PA-2
RF Amplifier with Slope Compensation
The 7703PA series provide amplification of RF signals in the satellite extended L-Band range. Adjustable slope compensation is included. Typical applications include amplification and slope compensation to boost weak signals, drive long coax runs or provide a high power signal for passive distribution systems.
All models occupy one card slot and can be housed in the 1RU 7801FR frame which holds up to four single or two dual slot modules, the 3RU 7800FR frame which has a 15 slot capacity, the portable 3RU 350FR frame which has a 7 slot capacity, or a standalone enclosure which holds a single module.
