Abstract: Techniques for designing baseband processing circuitry for radio IC's. In an aspect, techniques for differential-to-single-ended conversion in a baseband portion of the IC are disclosed to reduce the pin count and package size for RF IC's. In another aspect, the converter includes selectable narrowband and wideband amplifiers, wherein the wideband amplifiers may be implemented using transistor devices having smaller area than corresponding transistor devices of narrowband amplifiers. Further techniques for bypassing one or more elements, and for implementing a low-pass filter of the converter using an R-C filter network, are described.

Abstract: An integrated circuit (202) for transmit and receive matching is described. The integrated circuit (202) includes a transmit amplifier (DA). The transmit amplifier (DA) includes a first transistor (250), a second transistor (248) and a first inductor (LI). The first inductor (LI) couples the first transistor (250) to the second transistor (248). The integrated circuit (202) also includes a low noise amplifier. The low noise amplifier includes a third transistor (254), a fourth transistor (252), the first inductor (LI), a second inductor (L2), a third inductor (L3) and a transformer (279). The second inductor (L2) couples the first inductor (LI) to the third transistor (254). The third inductor (L3) couples the third transistor (254) to ground.
