The invention provides a software integrated radio superheterodyne receiver. The software integrated radio superheterodyne receiver comprises an antenna, a limiter, a first filter, a low-noise amplifier, a second filter, a mixer, a third filter and a zero-intermediate frequency receiving chip which are sequentially connected, wherein the zero-intermediate frequency receiving chip is connected to an MCU (microprogrammed control unit); the MCU is connected with a local oscillation chip; the local oscillation chip is connected to the mixer. The software integrated radio superheterodyne receiver has the beneficial effects that in case that the local oscillation leakage of the zero-intermediate frequency receiving chip is very big, a local oscillation signal can be filtered by the first filter and the second filter instead of being leaked to the outside, and the performance of the receiver can be effectively improved; in addition, the general zero-intermediate frequency receiving chip is high in gain and high in sensitivity, so that the chain length can be effectively reduced. The superheterodyne receiver is flexible to use, and different frequency points can be received by simply changing the first filter, the second filter and the local oscillation frequency.
