Abstract

The invention discloses an ultrashort wave broadband transceiver. The ultrashort wave broadband transceiver comprises a receiving circuit and a transmitting circuit. The receiving circuit comprises afirst filtering assembly, a first programmable attenuator, a first amplifier, a first filter, a first mixer, a second filter, a second amplifier, a second programmable attenuator, a second filtering assembly, an auxiliary gain circuit and a third amplifier which are electrically connected in sequence; the transmitting circuit comprises a third filtering assembly, a third programmable attenuator, afourth amplifier, a fourth filter, a second mixer, a fifth filter, a fifth amplifier and a first filtering assembly which are electrically connected in sequence. The ultrashort wave broadband transceiver is good in stability, low in cost and high in anti-interference capability.

Description

technical field [0001] The invention relates to the technical field of 500MHz-2500MHz radio frequency broadband transceiver, in particular to an ultrashort wave broadband transceiver. Background technique [0002] In the current transceivers, most of them adopt double frequency conversion technology, and the bandwidth is relatively narrow, usually hundreds of KHz to several MHz. The main disadvantages are as follows: [0003] (1) Two frequency conversion schemes are adopted, one mixed frequency local oscillator and two mixed frequency local oscillators need to be provided, two local oscillator frequency sources are required when transmitting and receiving the same frequency point, and four local oscillator frequency sources are required when transmitting and receiving different frequency points, and There is an intermediate frequency filtering and amplifying circuit between the first mixing frequency and the second mixing frequency. The scheme is complicated, the reliabilit...
