Background technology

With the development of radio communication, various wireless communication modules arise at the historic moment；Usual wireless communication module is launched Before, it is required for carrying out wireless communication module electric performance test and functional test, and carry out initial configuration.If no Directly wireless communication module is welded in equipment by test and used, once module goes wrong, this equipment will be caused to go out Existing failure, considerably increases the fraction defective of product, while also brings very big difficulty to maintenance and production；Additionally, due to difference The wireless communication module Default Value of producer is different from, and main control device will compatible different manufacturers wireless communication module simultaneously Initial configuration, the resource utilization of main control device is greatly reduced, also bring certain difficulty to exploitation.Therefore channel radio News test device plays vital effect to the normal use of wireless communication module.

However, with the continuous lifting for communicating chip design level to be measured, existing radio communication module function is more powerful, Number of ports quantity and form break through original limitation and become diversification.Therefore the test equipment of wireless communication signal it is also proposed more High performance and integrated level requirement.

The content of the invention

The utility model is directed to the awkward situation of prior art, it is proposed that a kind of wireless communication signal high-performance test module, with Phase provides the test Solution of higher performance, low energy consumption and duty.

The purpose of this utility model will be achieved through the following technical solutions：Wireless communication signal high-performance test module, face Participate in forming full frequency band radio frequency testing platform to chip to be measured and field programmable gate array, it is characterised in that：The test mould Block has chip AD9361 and its LNA integrated, active mixer, amplifier, DAC and ADC, wherein the chip AD9361 is equipped with the antenna receiving port of two-way independence by LNA, and the antenna transmitting of two-way independence is equipped with by amplifier Mouthful, and the chip AD9361 and programmable gate array interconnection two-way signaling interconnection.

Further, the chip AD9361, which matches somebody with somebody, is connected to configuration and itself is operated in reiving/transmitting state and several working method Initialization unit.

Further, the chip AD9361, which matches somebody with somebody, is connected to reference clock, and reference clock association access initialization Unit.

Further, the chip AD9361, which matches somebody with somebody, is connected to information input, the control unit of output data form.

Further, the chip AD9361 matches somebody with somebody the interface function unit for being connected to the extremely set frequency of fast lock and power consumption.

Further, the RF front ends that the chip AD9361 is also integrated with including at least I/Q modulator and RF Phase-Lock Loop are set It is standby.

Further, the amplifier is power amplifier driving amplifier.

Using the technical scheme of the utility model test module, its significant technique effect is embodied in：The test module branch 12 moduluses and the radio-frequency receiving-transmitting of digital-to-analogue conversion are held, send frequency band from 47MHz to 6GHz, frequency acceptance band carries from 70MHz to 6GHz High measurement sensitivity, noise response and synthesis precision.And it is synchronous with multi-chip, support CMOS/LVDS digital interfaces Ability.

Brief description of the drawings

Fig. 1 is the application system block architecture diagram of the utility model test module.

Fig. 2 is the interface circuit schematic diagram of the utility model test module and field programmable gate array.

Embodiment

The utility model is innovated for the testing requirement of existing communication platform chip or plate and proposes a kind of wireless telecommunications letter Number high performance test module, copes with various current main-streams, newly-designed wireless communication system is reliably tested.
