SELF-ACTIVATED TRANSFER SWITCH |
| 摘要 |
A self-activated transfer switch is disclosed. The self-activated transfer switch includes a transmit (TX) switch coupled between a TX port and an antenna port. A receive (RX) switch is coupled between the antenna port and an RX port, and RF-to-bias generator circuitry is coupled to the TX port and the antenna port. The RF-to-bias generator circuitry is configured to generate a bias signal to turn off the RX switch and turn on the TX switch when either of a TX signal is provided at the TX port and a jammer signal is received at the antenna port. The bias signal is generated from energy of at least one of the TX signal and the jammer signal. The TX switch is turned off and the RX switch is turned on when the bias signal is not being generated. |

1. A self-activated transfer switch comprising:
a transmit (TX) switch coupled between a TX port and an antenna port; a receive (RX) switch coupled between the antenna port and an RX port; and RF-to-bias generator circuitry coupled to the TX port and the antenna port and configured to generate a bias signal to turn off the RX switch and turn on the TX switch when either of a TX signal is provided at the TX port and a jammer signal is received at the antenna port, wherein the bias signal is generated from energy of at least one of the TX signal and the jammer signal, and wherein the TX switch is turned off and the RX switch is turned on when the bias signal is not being generated. |
