Saw-less receiver including transimpedance amplifiers

A surface acoustic wave (SAW)-less receiver comprises:

• a front end module (FEM) interface module operable to receive an inbound radio frequency (RF) signal;
• a radio frequency (RF) to intermediate frequency (IF) receiver section operable to:
• convert the inbound RF signal into a positive leg current RF signal and a negative leg current RF signal;
• convert the positive and negative leg current RF signals into an in-phase (I) mixed current signal and a quadrature (Q) mixed current signal;
• convert the I mixed current signal into an I mixed voltage signal;
• and
• convert the Q mixed current signal into a Q mixed voltage signal;
• and
• a receiver IF to baseband section operable to convert the I and Q mixed voltage signals into one or more inbound symbol streams.

A radio frequency (RF) to intermediate frequency (IF) receiver section comprises:

• a first inverter-based low noise amplifier module operable to amplify a positive leg of an inbound RF signal to produce a positive leg current RF signal;
• a second inverter-based low noise amplifier module operable to amplify a negative leg of the inbound RF signal to produce a negative leg current RF signal;
• a mixing module operable to convert the positive and negative leg current RF signals into an in-phase (I) mixed current signal and a quadrature (Q) mixed current signal;
• a first transimpedance amplifier module operable to convert the I mixed current signal into an I mixed voltage signal;
• and
• a second transimpedance amplifier module operable to convert the Q mixed current signal into a Q mixed voltage signal.
