A radio frequency repeater device includes a receive antenna that receives a receive signal having a first frequency. A transmit antenna transmits a repeat signal at the first frequency, the repeat signal being an amplified version of the receive signal. A signal filter communicates with the receive antenna and transmit antenna, the signal filter being operable to amplify quadrature and non-quadrature components of an input signal associated with the repeat signal to produce a filtered repeat signal. A coupler combines the receive signal with the filtered repeat signal in such a way that the filtered repeat signal cancels interference from the transmitted repeat signal in the receive signal.
