Claims (1)

  1. Сеть, объединяющая двухрежимные усилители мощности ВЧ-сигналов, имеет два ответвления, каждое из которых включает усилитель мощности. Первое ответвление включает усилитель мощности, работающий в нелинейном режиме, в то время как второе ответвление содержит усилитель мощности, работающий в линейном режиме работы. Ответвление нелинейного режима к тому же включает ВЧ-коммутатор. Оба ответвления соединены с общей выходной точкой соединения. Точка общего соединения соединена с фильтром перед выходом на антенну. Усилитель мощности в нелинейном режиме работает в том случае, когда ЧМ смещен в состояние отключения. Усилитель мощности в линейном режиме работает в том случае, когда должен быть усилен цифровой сигнал, в то время как нелинейный усилитель должен быть смещен в состояние отключения. ВЧ-коммутатор убирает нелинейный усилитель из цепи, чтобы исключить нагрузку для линейного усилителя, который находится во включенном состоянии.
