Embodiment

[0022] Such as figure 1 A novel W-band fundamental wave mixer shown includes a quartz substrate 1, and the quartz substrate 1 is provided with a radio frequency transition waveguide 2 connected in sequence, and an antiparallel terahertz GaAs Schottky mixing diode pair 3 , local oscillator transition waveguide 4 and intermediate frequency filter output circuit 5. The mixer with this structure has low frequency conversion loss, wide working bandwidth and intermediate frequency output bandwidth, simple process and high integration.

[0023] Specifically, the RF and LO signals are respectively input from the suspended microstrip port and the fin line port through the standard waveguide WR10, and two terahertz GaAs Schottky mixing diodes are installed on the fin line and the suspended microstrip in antiparallel form. Between the striplines, a balanced microstrip line suspension structure is formed; the intermediate frequency signal is led out from the SMA connector, and the W-band...

Abstract

The invention discloses a novel W-waveband fundamental wave frequency mixer. The frequency mixer comprises a quartz substrate, and the quartz substrate is internally provided with an RF transition waveguide, a Terahertz GaAs Schottky frequency-mixing diode pair in reverse parallel connection, a local oscillation transition waveguide and an intermediate-frequency filtering output circuit which are connected successively. The novel W-waveband fundamental wave frequency mixer is low in frequency conversion loss, wide in work bandwidth and intermediate-frequency output bandwidth, simple in technology and high in integrated degree.

Description

technical field [0001] The invention relates to the technical field of mixers, in particular to a novel W-band fundamental wave mixer. Background technique [0002] The W-band is an important window frequency in the millimeter wave, and the research on the transceiver technology in this band is a hot topic in the millimeter wave application at present. Due to its higher carrier frequency, W-band can support larger bandwidth and higher transmission rate. Because of the low atmospheric loss, W-band signals can be transmitted over long distances. Many applications of the W-band are inseparable from the receiving and processing of this frequency band. [0003] The mixer is one of the core components in the communication receiving system, which converts the frequency of the high-frequency carrier frequency signal into an intermediate frequency signal that can be processed. The performance of the mixer circuit directly affects the overall performance of the receiving system, wh...
