Abstract

The invention discloses a method for screening a 4-tube balanced terahertz frequency tripler based on direct current detection, and relates to the technical field of frequency multipliers. The methodcomprises the steps that the test position of a multimeter is adjusted to the test position of a diode; the red probe of the multimeter is connected with the core of an SMA head, and the black probe of the multimeter is connected with the cavity casing of a frequency multiplier; at the same time the multimeter displays the turn-on voltage of one of diode strings; the black probe of the multimeteris connected with the core of the SMA head, and the black and red probes of the multimeter are connected with the cavity casing of the frequency multiplier; at the same time the multimeter displays the turn-on voltage of another diode string; whether the performance of the 4-die terahertz balanced frequency tripler is qualified according to the tested numerical values of two turn-on voltages. Themethod is simple in process and can quickly screen out unqualified terahertz frequency triplers.

Description

technical field [0001] The invention relates to the technical field of frequency multipliers, in particular to a method for screening 4-tube balanced terahertz frequency triplers based on DC detection. Background technique [0002] Terahertz (THz) waves refer to electromagnetic waves with a frequency in the range of 0.3-3THz. The generalized terahertz wave frequency refers to 100GHz to 10THz, where 1THz=1000GHz. Terahertz waves have broad application prospects in high-speed wireless communication, radar, human body safety detection and other fields. To realize the transmission and reception of microwave, millimeter wave and terahertz frequency band signals, various microwave, millimeter wave and terahertz transmissions are inseparable. device, while the transmitting circuit is mainly based on a frequency multiplier made of frequency-multiplier Schottky diodes to achieve frequency multiplication of low-frequency millimeter-wave signals to the terahertz frequency band.
