Method of providing multiple voltage references to a radio-frequency device using a single analog line |
摘要 |
A method of providing multiple voltage references to a radio-frequency device using a single analog line includes the steps of setting the analog line voltage level to be a first reference voltage signal; instructing a first voltage reference device to memorize the first reference voltage signal by sending a first digital control signal to a digital line; providing the first reference voltage signal to the RF device via the first voltage reference device; re-setting the analog line voltage level to be a second reference voltage signal; instructing a second voltage reference device to memorize the second reference voltage signal by sending a second digital control signal to the digital line, the second digital control signal being different from the first digital control signal; and providing the second reference voltage signal to the RF device via the second voltage reference device. |

1. A method of providing multiple voltage references to a radio frequency (RF) device using a single analog line, comprising:
setting the analog line voltage level to be a first reference voltage signal; instructing a first voltage reference device to memorize the first reference voltage signal by sending a first digital control signal to a digital line; providing the first reference voltage signal to the RF device via the first voltage reference device; re-setting the analog line voltage level to be a second reference voltage signal; instructing a second voltage reference device to memorize the second reference voltage signal by sending a second digital control signal to the digital line, wherein the second digital control signal is different from the first digital control signal; and providing the second reference voltage signal to the RF device via the second voltage reference device, wherein the RF device is configured to receive a first frequency signal and a second frequency signal, and output a third frequency signal based on one of the first and second reference voltage signals. |
