FM amplifiers arerealized in MOSFET technology, as balanced amplifier with stripline 3 dB couplers or Wilkinson type dividers / combiners.
FM amplifiers with output power of 300 W, 600 W and 1 kW are standalone devices, while FM amplifiers with output power of 2 kW and 4 kW are realized with 1 kW amplifiers combined with Wilkinson combiner (at 2 kW level) and with 3 dB coupler (at 4 kW level)
