摘要： The invention provides a harmonic direct conversion mixer having a multiplier circuit comprising first and second mixers and a generator for generating two first and two second 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.

摘要： A subharmonic mixer circuit having an input stage (52) and a current modulating stage (64) is disclosed. The input stage (52) receives an RF input signal (RF+, RF-) at a first frequency and generates output currents (il, i2) varying in dependence upon the Rf input signal. The current modulating stage (64) comprises a first transistor (Q3) for receiving a first local oscillator signal (LOO) respective and a second transistor (Q4) for receiving a second local oscillator signal (LOl 80), 180 degrees out of phase with the first local oscillator signal, such that a modulating current signal (i0), having twice the local oscillator frequency, is superimposed onto the output currents.

摘要： A semiconductor circuit comprises a pair of transistors (11, 12) connected commonly at their collectors and emitters having their bases for receiving a first signal and its inverted signal, respectively; a transistor (13) connected between the common emitters and the ground potential and having a base for receiving a second signal; and an output circuit having an output load (51) connected between the common collector and a supply voltage (Vcc) to receive a third signal from the common collector. For low-voltage operation, the semiconductor circuit suppresses generation of even harmonics of a local oscillation signal.

摘要： A multi-tap, digital-pulse-driven mixer advantageously avoids local oscillator (11) leakage by shifting the local oscillator frequency (F LO ) out of the received frequency band. Low noise figures are advantageously realized by the use of digital pulses (51, 52) as mixer drive signals (16).

摘要： A transmission mixer (10) has a local input port (10 LO ) supplied with a local signal, an intermediate input port (10 in ) supplied with an input signal having an input frequency (f in ), a first output port (10 out1 ) for producing a first output signal having a first output frequency (f out1 ), and a second output port (10 out2 ) for producing a second output signal having a second output frequency (f out2 ). The first and the second output ports (10 out1 , 10 out2 ) are connected to first and second loads (LD1, LD2), respectively. The first load (LD1) is that where impedance-matching is made at the first output frequency (f out1 ) while the second load (LD2) is that where impedance-matching is made at the second output frequency (f out2 ).
