Description
Technical Field
The present invention relates to the field of electronic technologies, and in particular, to a radio frequency device and an electronic apparatus.
Background
In order to meet the explosive growth of data services of electronic equipment such as a mobile terminal and the like and the user perception requirements of users on novel service applications, mobile operators actively deploy network coverage with Carrier Aggregation (CA) 4G +, the downlink transmission rate is improved, and the user experience is improved.
However, a carrier aggregation band for a specific LB and MB, such as B8+ B3 of european operators, B12+ B4 of north american operators, or B17+ B4, is planned as follows: the uplink frequency band of B8 is 880-915MHz, and the second harmonic of B8 is 1760-1830 MHz; the uplink frequency band of B3 is 1710-1785MHz, and the downlink frequency band of B3 is 1805-1880 MHz; the uplink frequency band of B17 is 704-716MHz, and the third harmonic of B17 is 2112-2148 MHz; the uplink frequency band of the B4 is 1710-1755MHz, and the downlink frequency band of the B4 is 2110-2155 MHz.
As can be seen from the above data, the second harmonic of the transmit signal of B8 falls well within the receive band of B3, affecting the receive sensitivity of B3; the third harmonic of the transmitted signal of B17 falls well within the receive band of B4, affecting the receive sensitivity of B4.
When low-frequency B12 and B17 are used as main carriers and intermediate frequency is used as a secondary carrier, the third harmonic of B12 or B17 falls exactly within the receiving frequency band of B4 of the secondary carrier, and interferes with the sensitivity of B4, and the sensitivity of B4 is very severely reduced in actual measurement, which also occurs in the CA combination scenario of B8+ B3 in the same case.
Therefore, in the prior art, when the low frequency is used as the main carrier and the intermediate frequency is used as the auxiliary carrier, the harmonic of the low frequency will cause the in-band interference to the intermediate frequency, resulting in the back-off of the receiving sensitivity of the intermediate frequency.

and the second antenna is connected with the radio frequency transceiver and used for receiving the second frequency band signal and transmitting the second frequency band signal to the radio frequency transceiver under the condition that the first frequency band signal is used as a main carrier and the second frequency band signal is used as an auxiliary carrier.
