Patent WO-2020103450-A1 (WO)
Inventor: RAZMEHR NIMA
IPC: H04B1/02
Filed: 2019-06-26
Abstract: The disclosure relates to technology for attenuator circuits suitable for use at millimeter wavelength frequencies (super high to extremely high frequencies, such 60GHz for example). An input signal is received at a first hybrid coupler to generate two intermediate waveform signals, each of which is attenuated by a variable resistance and then recombined by a second hybrid coupler to provide the output signal for the attenuator. The first hybrid coupler isolates the variable resistors from the attenuator's input and the second hybrid coupler isolates the variable resistors from the attenuator's output. The variable resistors can be configured to provide wide range of attenuation values, such as from 0dB to 12dB. The value of the variable resistors can be controlled by a resistor calibration circuit configured to provide constant attenuation across process and temperature variations.
