Circuits for wireless communication on multiple frequency bands

A circuit for wireless communication comprising:

• a first quadrature hybrid having a first in port, a first iso port, a first cpl port, and a first thru port;
• a first mixer having a first input coupled to the first cpl port and having an output;
• a second mixer have a first input coupled to the first cpl port and having an output;
• a third mixer having a first input coupled to the first thru port and having an output;
• a fourth mixer having a first input coupled to the first thru port and having an output;
• a first filter having an input connected to the output of the first mixer and having an output;
• a second filter having an input connected to the output of the second mixer and having an output;
• a third filter having an input connected to the output of the third mixer and having an output;
• a fourth filter having an input connected to the output of the fourth mixer and having an output;
• and
• a first complex combiner having inputs connected to the output of the first filter, the output of the second filter, the output of the third filter, and the output of the fourth filter that provides first I and Q outputs based the output of the first filter, the output of the second filter, the output of the third filter, and the output of the fourth filter.
