The invention relates to the technical field of radar communication, and particularly discloses an electronic countermeasure-based miniaturized broadband transmit-receive frequency conversion module, which comprises a composite board (4), a metal partition board (6) and a digital board (8) which are arranged hierarchically from top to bottom, the composite board (4) is provided with an up-down frequency conversion channel. The digital board (8) is provided with a local oscillation source, a control circuit and a power supply circuit. High-frequency local oscillator signals between the composite board (4) and the digital board (8) realize cable interconnection through a first connector, and low-frequency signals between the composite board (4) and the digital board (8) realize vertical buckling interconnection through a second connector. According to the miniaturized transmit-receive frequency conversion module, the composite board (4) provided with the up-down frequency conversion channel and the digital board (8) provided with the local oscillator source, the control circuit and the power supply circuit are stacked up and down through the metal partition plate (6), and the connector is arranged to realize signal interconnection between the composite board (4) and the digital board (8), so that good isolation of physical signals is realized in space; and the miniaturization stacking design of the product is met.
Description
technical field [0001] The invention relates to the technical field of radar communication, in particular to a miniaturized broadband transceiver and frequency conversion module based on electronic countermeasures. Background technique [0002] The transceiver frequency conversion module refers to an integrated module that can not only realize the down-conversion receiving function of the radio frequency RF signal to the intermediate frequency IF, but also realize the up-conversion transmission function of the intermediate frequency IF signal to the radio frequency RF signal. In order to solve the crosstalk problem between receiving and sending signals, the traditional transceiver frequency conversion module will design the receiving channel and the transmitting channel completely independently, resulting in the inability of the local oscillator of the receiving channel and the local oscillator of the transmitting channel to interoperate, and the low product integration level...
