A dual-band low-noise amplifier circuit includes an amplification sub-circuit and a switch frequency selection circuit; the amplification sub-circuit is used for performing gain amplification on a radio frequency signal to be amplified to obtain an amplified radio frequency signal, and outputting the amplified radio frequency signal; the switch frequency selection circuit is connected to the amplification sub-circuit, and is used for controlling the state of a switch in the switch frequency selection circuit on the basis of a target frequency band corresponding to the radio frequency signal to be amplified, so that the dual-band low-noise amplifier circuit meets optimal performance in the target frequency band. In this way, low-noise amplification of dual-band signals is achieved by means of the reconfigurable structure of the low-noise amplifier circuit, and parameters such as noise figure, gain, and linearity can be kept in optimal states in each frequency band.

The present invention relates to the technical field of natural medicines, and in particular to a triterpenoid compound with an effect of improving glucose and lipid metabolism disorders, and preparation and application thereof. A novel triterpenoid compound was obtained by separation fromL. for the first time in the present invention. Studies on a mouse primary hepatocyte model and a 3T3-L1 preadipocyte model show that the novel triterpenoid compound in the present invention has activity of regulating glucose and lipid metabolism, and after combination with known triterpenoid compound Momordicoside G, the activity of regulating glucose and lipid metabolism is significantly higher than that of a single compound at the same dose, indicating that the novel triterpenoid compound and a complex thereof in the present invention can be used to improve glucose and lipid metabolism disorders and provide a new way for diabetes treatment.
