摘要： An improved local oscillator (LO) driver circuit for a mixer, the LO driver circuit includes a gain circuit responsive to LO input signals at a predetermined LO frequency range. At least a first pair of a parallel combination of a resistor and a capacitor is coupled to the gain circuit and to LO inputs of the mixer. The resistor configured to increase impedance at low frequencies of the frequency range and the capacitor is configured to reduce the impedance of the first parallel combination at high frequencies of the frequency range to reduce resistive impendence of the resistor. At least a second pair of a parallel combination of a low quality factor inductor and a high quality factor inductor is connected to the first pair. The second pair in serial combination with the first pair is tuned to provide a constant desired load impedance and a constant desired voltage swing at the LO inputs of the mixer over the predetermined LO frequency range.

摘要： An RF detector configured to provide two outputs, one being a function of the true RMS power level of an RF input signal, and the other being a function of the instantaneous/peak power of the RF input signal, normalized to the average power level. The RF detector includes a variable gain detection subsystem including a single detector or detector array that provides a representation of the power level of the RF input signal. The detector or detector array is common to both the RMS power detection channel and the instantaneous/peak power detection channel of the RF detector. A method of RF detection includes providing representations of the RF input signal at different gain levels, selecting one or more of the representations, and averaging the selected signals. The gain levels of the selected representations is adjusted to provide information about the average power level of the RF input signal.
