摘要： When a power supply switch is turned on and an RF signal and an LO signal are input to a bipolar transistor, a mixed signal of both signals is output as an IF signal. When the power supply switch is turned off, the bipolar transistor operates as two diodes connected between a base terminal and an emitter terminal and between the base terminal and a collector terminal. When the IF signal and the LO signal are input, the input signals are mixed with each other by the diodes and the RF signal is output. Accordingly, one frequency conversion has a plus conversion gain and when bidirectional frequency conversion is performed by the use of one frequency converter, an external circuit such as a signal path switching switch is not necessary.

摘要： Circuit 200 comprises an input amplifier stage 290, phase-splitters 292, 293 and mixer cores 294, 295. An input signal is applied to terminal 220, a local oscillator signal applied to terminals 230, 231 and a 90° shifted local oscillator signal is applied to terminals 232, 233. The In-phase differential signal is output at terminals 240, 241 and the quadrature signal is output at terminals 240, 233. Phase-splitters 292, 293 comprise base-coupled transistors 202, 203, 205, 206 which are biased by a potential applied to terminal 262. As these phase-splitters are driven by input amplifier stage 290, which acts as a current source, the arrangement has very good noise properties. Degeneration inductor 280 reduces the noise figure of the circuit further because it is a noiseless component. Phase-splitters 292, 293 and mixer cores 294, 295 are preferably cross-coupled to allow cancellation in phase-splitters 292, 293 of the second harmonic of the local oscillator signal generated at the inputs to mixer cores 294, 295.
