Flexible screen curled circuit board

The invention discloses a flexible screen curled circuit board, and relates to the field of curled circuit boards. Comprising a low-noise amplifier which is used for enhancing weak signals and providing better input signals for subsequent devices under the condition that the signal-to-noise ratio of the low-noise amplifier is not influenced; the stability circuit is used for ensuring the normal work of the low-noise amplifier; according to the flexible screen curled circuit board, firstly, selection of a mixer circuit structure and working frequency is carried out according to the performance of a flexible radio frequency monocrystalline silicon thin film transistor, then working point selection and flexible impedance matching network design in a flexible frequency mixing design process are described, and performance parameters of a flexible mixer are represented. Results of influence of non-ideal characteristics and bending stress of a flexible device on circuit performance show that linearity change of the
