CPM modulation good resistance to non-linearities use of a Modulation Transfer Loop (MTL) for RF
conversion of IF signal use of saturated RF amplifiers (increased output
power and reduced power consumption) use of carrier frequency multiplication

sSRA L Split VersionProtected Terminal
Hot Stand-by Configuration
• Dual antenna solution - No additional RF losses due to RF couplersand waveguide use
- Easy installation (each ODU is directly mountedon the back of its antenna)
- Normally used for 20 and 30 cm diameter antennas- Space diversity improvement
• Single antenna solution - Smaller environmental impact - Better wind loading resistance- Normally used for 60 or 120 cm diameter antennas- Main path loses only 1 or 1.5 dB of system gain
