Abstract

The invention discloses an ultra-wideband miniaturized radio frequency module. An input signal passing a low pass filter A (1) and a limiter (2) and a calibration signal passing a single knife doublethrow switch A (3) are selected by a single knife double throw switch B (4), and then selected through a single knife four throw switch A (5); then power control is performed through a low noise amplifier A (6), a low noise amplifier B (7), a direct connector (8) and one of the four ways of a fixed attenuator; then power adjustment is performed through a single knife four throw switch B (10), a numerical attenuator (11) and an amplifier A (12); then selection is carried out by a single knife six throw switch A (13), and frequency selection is carried out through one of the six ways of a band-pass filter; and a local oscillator signal passes a mixer (26) and a low pass filter B (27) to obtain an intermediate frequency signal. The ultra-wideband miniaturized radio frequency module solves theproblems of the ultra-wideband low noise design, the gain flatness control, the anti-interference and the miniaturization.

Description

technical field [0001] The invention relates to a radio frequency component, in particular to an ultra-wideband miniaturized radio frequency component. Background technique [0002] In the past, RF components consisted of limiters, microwave switches, attenuators, mixers, filters, power splitters and amplifiers, etc. After microwave signals were received through the main channel or calibration channel, they were selected by a single-pole double-throw switch and then fed into the The channel expands the dynamics through the attenuator after limiting the protection, enters the mixing frequency after amplification and filtering, and obtains the intermediate frequency signal after the mixing amplification and filtering. Because the frequency band is too wide, the number and types of components required are huge, which affects the performance of components. And because of the high process requirements, the integration is poor, the receiving bandwidth cannot be very wide, the nois...
