摘要： A HEMT cell includes two or more gallium nitride ("GaN") high-electron-mobility transistor ("HEMT") devices electrically connected in series with each other. The HEMT cell includes a HEMT cell drain, a HEMT cell source, and a HEMT cell gate. The HEMT cell drain connects with the drain of a first GaN HEMT device in the series. The HEMT cell source connects with the source of a last GaN HEMT device in the series. The HEMT cell gate connects to a first two-dimensional electron gas ("2DEG") gate bias resistor that connects with the gate of the first GaN HEMT device. The HEMT cell gate connects to a second 2DEG gate bias resistor that connects with the gate of the second GaN HEMT device. The first and second 2DEG gate bias resistors are located in a 2DEG layer of the HEMT cell. A multi-throw RF switch is also disclosed.

摘要： A method and apparatus are provided for providing improved radio frequency (RF) receiver signal correction. For RF receiver circuitry (106) having receive path and a warmup period associated therewith and including at least one analog baseband gain control stage (218) having a gain associated therewith, the method includes the step of performing a DC correction calculation operation during the warmup period to derive a DC correction value having a first component and a second component for each of the at least one gain control stage (218). The DC correction calculation step includes the steps of performing a first closed loop correction (460) of a baseband path to derive the first component of the DC correction value and performing a second closed loop correction (462) of the receive path as a function of the (218) gain during the warmup period to derive the second component of the DC correction value. During operation after the warmup period (464, 466), an open loop correction is performed for instantaneous DC correction as function of the PMA (218) gain and the DC correction value.
