Abstract

The invention relates to the field of electronic technology, in particular to a novel composite UWB electronic tag. Described a kind of novel composite UWB electronic label, comprises: ultra-wideband antenna, the first duplexer, the second duplexer, power amplifier, low noise amplifier, attenuator and MCU chip; One end of power amplifier connects the first duplexer The other end is connected to the second duplexer; one end of the low noise amplifier is connected to the attenuator, and the other end is connected to the first duplexer; the attenuator is connected to the second duplexer; the MCU chip is connected to the first duplexer and the second duplexer device. The receiving signal and the transmitting signal of the electronic tag are switched through the first duplexer and the second duplexer, wherein a power amplifier is set on the transmitting path, so that the power of the transmitting signal is increased, and the ability to withstand interference is improved. A low noise amplifier is set on the receiving path, which can reduce the receiving noise figure and improve the receiving sensitivity.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a novel composite UWB electronic tag. Background technique [0002] Ultra Wideband (UWB for short) is a carrier-free communication technology that uses nanosecond to microsecond non-sine wave narrow pulses to transmit data, and can use its sub-nanosecond ultra-narrow pulses to do close-range accurate indoor Positioning, the accuracy can reach about 10 cm, and it has the advantages of low power consumption, strong anti-interference ability, and strong anti-multipath effect ability. [0003] Although UWB technology has obvious advantages in the application of short-distance high-speed data transmission, whether it is a single pulse signal or a multi-pulse signal, its transmission power is limited, and it cannot resist burst interference and effective long-distance communication. Therefore, in some special applications such as military and mine communications, communications ar...
