摘要： 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.

摘要： 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.

摘要： A phase locked loop includes a buffer that synchronizes the transmission of the new count value to the completion of the previous count to avoid errors caused by dithering. The buffer is connected to a count input of the counter and transmits the new count upon receipt of the carryout signal from the counter. Alternatively, the transmission of the new value of N from the buffer is delayed after receipt by the buffer of a carryout signal from the counter. In another embodiment, a delayed version of the carryout signal is used to trigger the buffer to transmit the new count value to the counter. In another feature, a buffer synchronizes phase data to a reference signal before inputting it to a digital modulator of the phase locked loop.
