System providing reduced intermodulation distortion |
| 摘要 |
A system divides a signal into first and second portions and transmits the first and second portions through different signal paths between a first port and a second port. Each of the signal paths comprises an amplifier arranged in sequence with a passive device. Phase shifters may be included in each of the signal paths to produce cancellation of intermodulation products by destructive interference. |

1. A system, comprising:
a first port configured to receive a transmit signal; a second port configured to transmit the transmit signal; a first transmit path configured to transmit a first portion of the transmit signal from the first port to the second port and comprising a first transmit amplifier followed by a first frequency filter; and a second transmit path configured to transmit a second portion of the transmit signal from the first port to the second port and comprising a second transmit amplifier followed by a second frequency filter, wherein the first and second frequency filters have substantially the same phase responses and amplitude responses as each other. |
