What is the purpose of the Improved Frequency Modulation (IFM) amplifier?

Explanation:
The key idea is that the IFM amplifier sits in the transmit path and increases the RF power available for SINCGARS transmissions. By delivering more output power, it strengthens the signal across distance and through the frequency-hopped channels, improving the link margin and reliability. It doesn’t affect receiver sensitivity, which comes from the receiver front end, nor does it reduce power consumption or increase antenna gain—those are determined by different parts of the system. So the purpose is to provide additional output power capabilities for optimum SINCGARS transmissions.
