摘要： PROBLEM TO BE SOLVED: To minimize a transmission loss while suppressing complexity of a circuit configuration by constituting so that a resistor indicates a minimum attenuation regarding a useful signal in an intermediate frequency of an intermediate frequency filter and terminates an output of a mixer at a system impedance in all the other frequencies. SOLUTION: This device is a heterodyne mixer which includes a mixer 1 having a separation filter 3 terminating an output terminal in a wide band and an intermediate frequency filter 5, and a resistor having a system impedance is disposed between the separation filter 3 and the intermediate frequency filter 5. Then, it is constituted so that the resistor is connected to a resonance element synchronized with the intermediate frequency, the connection indicates a minimum attenuation regarding a useful signal in the intermediate frequency of the intermediate frequency filter 5 and terminates an output of the mixer 1 in all the other frequencies.

摘要： For measuring electronic devices under test with a network analyzer, the electronic devices to be embedded into a linear auxiliary network during their operation, as well as, during the measurement. First, system error correction data is determined for the network analyzer according to a known calibration method by connecting calibration standards. Then, the characteristic data for the auxiliary network to be used is determined and is linked with the system error correction data to form new error correction simulation data. Finally, in the subsequent measurement of devices under test connected to the network analyzer, this error correction simulation data is appropriately considered with the algorithm for system error correction that is present in the network analyzer, so that an auxiliary network virtually connected to the device under test is simulated.

摘要： An aspect of the present invention is a voltage controlled oscillator that provides multi octave band tenability. The oscillator preferably includes one or more multi planar resonators which allow it to be implemented in integrated circuit form. Oscillators implemented in accordance with the aspect of the present invention provide as wide a tuning range as the YIG based resonators but are much more compact and efficient. Therefore, they are amenable to implementation in integrated circuits and suited for adaptation in third and future generation wireless devices.
