Description
Technical field
The present invention relates to radio communication and radio circuit design field, especially receiver radio frequency front end system structure.This
Invention is specifically related to a kind of while the receiver of two channel signals of reception, by the way of frequency division multiplexing, uses a reception
Machine receives two paths of signals simultaneously, and to this two paths of signals while down coversion, converts it to low frequency, be easy to digital circuit to carry out
Processing.
Background technology
Communication system can be communicated by the way of frequency division multiplexing, to improve the efficiency of communication.But to different frequencies
The signal of section, or by the way of multi-frequency multi-mode, by different configurations, timesharing receives signal, or for different hairs
Signal is penetrated, a few set receiving devices are respectively adopted, are received in different frequency ranges, to improve the efficiency of system.Multi-frequency multi-mode connects
Receipts machine is using a receiver, although by different settings, can receive the signal of different frequency range, but can not receive simultaneously not
With the signal of frequency range, and need to switch local frequency, start wave filter etc., the time for setting up receiving channel is longer, and right
Each road signal is unable to global optimization.To many set receiver systems, while multiple signals are received, as a result of many set circuit moulds
Block, power consumption is multiplied.
The content of the invention
It is an object of the present invention to provide a kind of receiver system structure, low-power consumption is wanted to meet wireless radio frequency receivers
Ask.
In order to solve the above problems, the present invention provides a kind of two-channel receiver system, including:Low-noise amplifier, together
Oscillator phase, quadrature oscillator, inphase mixer, orthogonal mixer, with phase variable gain amplifier, orthogonal variable gain amplification
Device, adder, positive frequency complex filter and negative frequency complex filter.
The rf inputs of inphase mixer and orthogonal mixer all connect the output of low-noise amplifier, inphase mixer
Local oscillator port connect the output of phase-synchronized oscillator, the local oscillator port of orthogonal mixer connects the output of quadrature oscillator.
The output of inphase mixer and orthogonal mixer is directly added, and exports multiple to positive frequency complex filter and negative frequency
Wavenumber filter.
Positive frequency complex filter reserve channel I inband signaling, suppresses out-of-band interference；Negative frequency complex filter retains
Passage Q inband signaling, suppresses out-of-band interference.
