Embodiment Construction

[0012] combine figure 1 , the integrated millimeter-wave up-conversion components are composed of local oscillator frequency multipliers, local oscillator filters, local oscillator amplifiers, mixers, radio frequency amplifiers, filters, gain amplifiers, power drive amplifiers, final power synthesis amplifiers and detectors device to connect. First, the local oscillator output signal is frequency multiplied. After frequency multiplication, since the output signal includes unnecessary multiple harmonics and fundamental components, it is necessary to add a band-pass filter at the output of the frequency multiplier to obtain the second harmonic component. The signal obtained at this time is small and needs to be amplified, so a local oscillator amplifier is added; then the frequency multiplied local oscillator signal is mixed with the intermediate frequency signal, in order to better suppress out-of-band spurs, after mixing Connect a first-stage high-gain RF amplifier first, and...

Description

a technical field [0001] The invention relates to a millimeter-wave component, in particular to a high-power millimeter-wave up-conversion power amplifier component based on a three-branch synthesis network. Two background technology [0002] Millimeter-wave up-conversion components are key components in millimeter-wave systems and can be widely used in millimeter-wave communications, radar, and telemetry and remote control. Millimeter-wave up-conversion components have been reported at home and abroad, such as Document 1: "Millimeter-wave frequency doubling up-conversion power amplifier components", Semiconductor Information, 2000.8. This component multiplies the input signal (15GHz, 10dBm) to 30GHz, upconverts the local oscillator signal (5GHz, 10dBm) to 35GHz, and then amplifies the output power. The frequency doubling part adopts GaAs PHEMT active frequency doubling and amplification, and the frequency mixing circuit adopts double-balanced frequency mixing of GaAs diode...
