Architecture to reject near end blockers and transmit leakage

An apparatus for minimizing transmit signal interference, comprising:

• an antenna;
• a low noise amplifier;
• a transformer;
• a mixer,
• an RC filter;
• a main biquad filtering path;
• and
• at least one auxiliary biquad filtering path.

An apparatus for minimizing transmit signal interference, comprising:

• means for receiving a signal;
• means for amplifying the received signal;
• means for mixing the received signal with an intermediate frequency signal to obtain a baseband modulated signal;
• means for filtering the baseband modulated signal in a first filter;
• means for dividing the first filtered baseband modulated signal by a preselected amount;
• means for sending a first divided portion of the baseband modulated signal to a main path of a biquad filter, producing a first biquad filtered signal;
• means for sending a second divided portion of the baseband modulated signal to an auxiliary path of the biquad filter, producing a second biquad filtered signal;
• means for recombining the first biquad filtered signal with the second biquad filtered signal before a second stage of the biquad filter;
• and
• means for filtering the recombined biquad filtered signal in the second stage of the biquad filter.

A non-transitory computer readable media including program instructions which when executed by a processor cause the processor to perform a method of comprising the steps of:

• receiving a signal;
• amplifying the received signal;
• mixing the received signal with an intermediate frequency signal to obtain a baseband modulated signal;
• filtering the baseband modulated signal in a first filter;
• dividing the first filtered baseband modulated signal by a preselected amount;
• sending a first divided portion of the baseband modulated signal to a main path of a biquad filter, producing a first biquad filtered signal;
• sending a second divided portion of the baseband modulated signal to an auxiliary path of the biquad filter, producing a second biquad filtered signal;
• recombining the first biquad filtered signal with the second biquad filtered signal before a second stage of the biquad filter;
• and
• filtering the recombined biquad filtered signal in the second stage of the biquad filter.
