Abstract
A method for transforming single-ended signals outputted from a low-noise amplifier of a wireless transceiver into differential signals. The method includes: providing a transformer according to a default requirement of the wireless transceiver; transferring the single-ended signals provided by the low-noise amplifier to a first end of a primary end of the transformer, and coupling a second end of the primary end of the transformer to a power source; grounding a center tap of a secondary end of the transformer; and outputting the differential signals from two ends of the secondary end of the transformer.
