    • One embodiment of the present invention relates to a test signal generator configured to generate a single sideband (SSB) test signal that is used for testing components of one or more receiver chains to identify errors in the receiver chains. In one embodiment, the circuit comprises a SSB signal generator configured to generate an IQ baseband signal comprising a sequence of constellation points corresponding to the SSB test signal. The constellation points are modulated onto a high frequency local oscillator signal to generate the SSB test signal, which is inserted into a reception path of a receiver at a test signal injection point. The reception path comprises a mixer configured to mix the SSB test signal with the local oscillator signal to generate a down-converted, intermediate frequency output signal. The output signal may be analyzed to determine errors in the reception path.

    • A tuned switching power amplifier having a switch for receiving an AC input signal. The switch controls the application of DC power to a load through a load network. The load network develops a parallel inductance and a parallel capacitance across the switch that minimizes power losses associated with the switch by creating a transient response across the switch that insures that, when the switch transitions from on to off, the voltage across the switch remains low until the current trough the switch reaches zero, and that, when the switch transitions from off to on, the voltage across the switch is zero and has a substantially zero time derivative prior to when the switch transitions from off to on. The parallel inductance is developed by a transmission line of a determined electrical length.
    • 一种具有用于接收AC输入信号的开关的调谐开关功率放大器。 交换机通过负载网络控制对负载的直流电力的应用。 负载网络在开关之间形成并联电感和并联电容,通过在开关上产生瞬态响应来最大限度地减少与开关相关的功率损耗,确保当开关从开关转换到断开时,开关两端的电压保持低电平 直到开关达到零,并且当开关从断开转变为导通时,开关两端的电压为零,并且在开关从断开转换到导通之前具有基本为零的时间导数。 并联电感由确定的电长度的传输线显影。
