Abstract

The invention provides a silicon-based three-dimensional integrated frequency conversion channel, and relates to the technical field of microwave electronics. The invention discloses a silicon-based three-dimensional integrated frequency conversion channel which comprises a multi-way switch filter module and a frequency conversion receiving and transmitting module. Wherein the multi-way switch filter module comprises a first single-pole multi-throw switch, a filter bank and a second single-pole multi-throw switch which are connected in sequence. The frequency conversion transmit-receive module comprises a primary frequency conversion transmit-receive unit and a secondary frequency conversion transmit-receive unit. The primary frequency conversion transmit-receive unit is connected with the first single-pole multi-throw switch, and the secondary frequency conversion transmit-receive unit is connected with the second single-pole multi-throw switch. By adopting the scheme of combining the two-stage frequency conversion structure and the multi-path switch filter bank, the broadband frequency conversion and better cross modulation suppression and spurious suppression effects are realized more easily, and the spurious suppression performance of the frequency conversion channel is improved.

Description

technical field [0001] The invention relates to the technical field of microwave electronics, in particular to a silicon-based three-dimensional integrated frequency conversion channel. Background technique [0002] With the rapid iteration of mobile communication and radar technology, active phased array technology has been more and more widely used in military and civilian electronic equipment. At present, active phased array radar urgently pursues high sensitivity, high resolution, anti-interference, miniaturization and other performance, and puts forward strict requirements on the stray suppression, light weight, miniaturization and other indicators of the RF front-end circuit. [0003] However, the current common frequency conversion channel lacks the filter segment suppression method, resulting in poor spurious suppression capability. SUMMARY OF THE INVENTION [0004] (1) Technical problems solved [0005] In view of the deficiencies of the prior art, the present i...
