RF transmit architecture methods
View Patent ↗A transmitter device is switchably operable in a digital IQ mode (DIQM) of operation and a polar mode (PM) of operation. The device has a switch logic processor that determines an attribute of operation of the transmitter device. When a first condition of the attribute is met, the switch is to switch to or remain in the PM, and when a second condition of the attribute is met, the switch is to switch to or remain in the DIQM. The attribute may be: a modulation bandwidth to be used during a transmission time slot, whether a transmission is to be a non-contiguous single-carrier transmission or a non-contiguous multiple-carrier transmission, a contiguous single-carrier transmission or a contiguous multiple-carrier transmission, whether a low or high EVM mode transmission is to be used during a transmission time period, whether an LTE, a 5G, or a Wi-Fi mode transmission is to be used, among others.

the attribute is whether a low or high error vector magnitude (EVM) mode transmission is to be used during a transmission time period;
the first condition is that the transmission is to be a low EVM transmission; and
the second condition is that the transmission is to be a high EVM transmission.
2. The transmitter device of claim 1 , wherein:
the low EVM transmission utilizes a 64-Quadrature amplitude modulation (QAM) or lower order modulation scheme; and
the high EVM transmission utilizes a 256-QAM or higher order modulation scheme.

a switch logic processor to determine an attribute of operation of the transmitter device; and
a switch connected to the switch logic processor and that is to switch operation of the transmitter device between the DIQM of operation and the PM of operation, wherein when a first condition of the attribute is met, then the switch is to switch to or remain in the PM, and when a second condition of the attribute is met, then the switch is to switch to or remain in the DIQM; wherein, in a dual band mode of operation, a first band uses PM and a second band uses DIQM.
4. A method for operating a transmitter device that is switchably operable between a digital IQ mode (DIQM) of operation and a polar mode (PM) of operation, the method comprising:
determining with a switch logic processor, an attribute of operation of the transmitter device;

determining with a switch logic processor, an attribute of operation of the transmitter device;
when a first condition of the attribute is met, switching to or remaining in the PM; and
when a second condition of the attribute is met, switching to or remaining in the DIQM;
wherein, in a dual band mode of operation, a first band uses PM and a second band uses DIQM.
7. A computer program product comprising one or more tangible computer readable non-transitory storage media comprising computer-executable instructions operable to, when executed by processing circuitry of a device, configure the device to:
operate a transmitter device that is switchably operable between a digital IQ mode (DIQM) of operation and a polar mode (PM) of operation, to:
determine, with a switch logic processor, an attribute of operation of the transmitter device;
when a first condition of the attribute is met, switch to or remain in the PM; and
