摘要： The invention provides a harmonic direct conversion mixer having a multiplier circuit (10) comprising first and second mixers and a generator (20) for generating two first (21, 22) and two second (23, 24) control signals for controlling the first and second mixers. The control signals are balanced signals and are provided in four phases shifted by pi /2 in phase. The frequency of the control signals is different from the frequency of the mixer input signal (19).

摘要： An automatic gain controller for transceiver elements uses a digital topology to achieve an efficient and rapid gain settling so that an output signal of a variable gain section (110) is within a predefined range. In one embodiment, an input signal is periodically sampled and latched so as represent the gain excess of the variable gain section (110). An accumulator (150), including an adder (155) having saturation characteristics and a latch (156) as a feedback element, creates a number for a new gain setting so that the variable gain section may adapt to the new gain setting within one clock period. In one example, a gain range of 84dB is controllable and settling is achieved within 3 clock periods at most.
