Auto Up-Link Power Controller
Jisnu’s AUPC is a micro controller-based system which is used to control the Up-link power proportional to the attenuation experienced in the received signal strength. The unit accepts L-Band Signal (950 to 2150 MHz) from the Modem in the Down-Link chain
and AGC voltage from the Beacon Tracking Receiver depending on which it adjusts the level in Up-Link chain. The level adjustment is possible upto 20 dB in steps of 0.1 dB to 0.5 dB (selectable), used in C, Ext-C, Ku
and Ka Band uplink transmission Stations.
Applications
- SATCOM application with high fading condition in higher frequency band.
- Automatic Output power control without human interference.
- Covers complete L band Range (950 MHz to 2150MHz)
- User selectable rain attenuation range 10 dB/20 dB
- Failsafe path
- Automatic correction of rain fading in Ku & Ka band
- User Friendly MMI
- Ethernet for remote application
