Abstract: An apparatus, including: a clock source configured to generate a local oscillator (LO) clock signal; a radio frequency digital-to-analog converter (RF DAC) configured to generate a radio frequency (RF) signal based on a data signal and the LO clock signal; and an idle data detector configured to: detect a stream of idle data in the data signal; and disable providing the LO clock signal to at least a portion of the RF DAC in response to detecting the stream of idle data.

Abstract: An apparatus including: a transmitter output impedance matching circuit including an inductive element; a low noise amplifier (LNA) including a first field effect transistor (PET); a receiver input impedance matching circuit, including: a transformer including a first winding and a second winding; and a capacitor coupled in series with the first winding between a first end of the inductive element and a gate of the first FET, wherein the second winding is coupled to a second end of the inductive element; and a radio frequency (RF) port coupled between the first end of the inductive element and the capacitor.
