Abstract
A transceiver is described that includes a power amplifier (PA), a low noise amplifier (LNA), and an impedance matching circuit having a first and second differential output node. The first and second differential output nodes are coupled to outputs of the PA and to inputs of the LNA. The impedance matching circuit provides a load impedance to the outputs of the PA. The transceiver further includes a first impedance device having an output impedance coupled between the first and second differential output nodes. In this way, the combination of the output impedance and the load impedance matches with an impedance at the inputs of the LNA.
