Miniaturized channel with low power consumption at Ka frequency band

Abstract

The invention relates to a miniaturized channel with low power consumption at the Ka frequency band. The miniaturized channel comprises a public passageway, a first passageway, a second passageway, a public local oscillator, a first passageway local oscillator and a second passageway local oscillator. Through design of frequency points of the public local oscillator, the first passageway local oscillator and the second passageway local oscillator and design of the framework of the public passageway, the first passageway and the second passageway, the number of the channels and the number of the local oscillators of a dual-passageway variable-frequency channel are reduced, the number of active devices is reduced, channel power consumption is greatly lowered, miniaturized design of the channel is achieved, and a high-dynamic, low-stray and dual-passageway miniaturized receiving channel with lower power consumption at the Ka frequency band is formed; in addition, automatic gain amplifiers in the two passageways are creatively designed, the base band is used for processing exiting resources, automatic and controllable gain amplification is achieved through the mode that analog and digital are combined, the number of detectors and the number of A / D samplers are reduced, resources are saved, cost is lowered, and precision is greatly improved.

Description

technical field [0001] The invention relates to a Ka-band low-power miniaturized channel, which belongs to the technical field of measurement and control. Background technique [0002] High-speed aircraft put forward higher requirements on the information processing capability and anti-"black barrier" ability of the telemetry system. Therefore, the requirements of the telemetry system on the modulation code rate, the electromagnetic compatibility performance of the equipment, and the general flexibility of the equipment are gradually increased. The modulation code rate is changed from the traditional The 2Mbps of the network is increased to 10Mbps, the requirement for the bandwidth of the analog channel is increased to more than 20MHz, and the number of radio frequency channels is increased. [0003] Traditional telemetry channels have two disadvantages that are not conducive to use on aircraft: [0004] 1. The channel structure is independently designed, and the connector ...

AI Technical Summary

Problems solved by technology

[0003] Traditional telemetry channels have two disadvantages that are not conducive to use on aircraft:

[0004] 1. The channel structure is independently designed, and the connector connection is complicated, which makes the channel structure too large and cannot meet the requirements of light weight and miniaturization of the bomb load.

[0005] 2. The functions of multiple channels are independent, the use of electronic components is large, and the power consumption is large, which increases the output burden of the system battery and requires high heat dissipation for the whole machine
