When transmitting satellite signals, RFIC102 is responsible for converting baseband signals generated by modem101 into radio frequency signals, and sending the radio frequency signals to PA105 for power amplification, and then transmitting the signals through filter circuit 106 and T/R switch 107, and then transmitting the signals from satellite antenna 110.

When receiving satellite signals, the satellite antenna 110 transmits the received satellite signals to a receiving channel, the satellite signals are amplified by the filter circuit 104 and the LNA103, then the satellite signals are converted into baseband signals by the RFIC102 and transmitted to the modem101 for demodulation, the power supply part of the PA105 outputs VPH signals to DCDC after the battery voltage passes through the PMIC108, and the power is supplied to the PA105 by a boosting DCDC 109.

Then, the system switches to the satellite antenna 212 of the S frequency band, sends the received satellite signal of the S frequency band to the downlink channel of the S frequency band, amplifies the signal by the filter circuit 204 and the LNA203 of the S frequency band, then sends the signal to the RFIC202 of the beidou satellite for down-conversion to a baseband signal, and then completes the demodulation of the baseband signal by the beidou modem201, and obtains the signal of the satellite radio positioning system (Radio Determination SATELLITE SYSTEM, RDSS).

When transmitting satellite signals, the system is switched to an L-band satellite antenna 213, the modem201 generates Beidou baseband signals, the Beidou baseband signals are converted into L-band radio frequency signals through the RFIC202, and then the satellite signals are transmitted to satellites through the satellite antenna 213 through the Beidou PA207 and the filter circuit 208.

However, under the existing mobile phone architecture, only one set of systems of the space satellite system and the Beidou satellite system is generally supported. The two sets of systems have different working flows, have advantages and disadvantages, have stronger functions of space satellite communication, are more complex, have higher power consumption, are required to be paid for use by users, have relatively simple Beidou satellite communication and lower power consumption, and can be used for free by users. However, only one of the systems is currently supported, resulting in inefficiency in satellite communications.

s902: and sending control instructions to the transceiver and the signal processing chip.

Here, when the beidou satellite is used for transmitting satellite signals, the target receiving and transmitting link determined by the electronic equipment is a first transmitting link, when the beidou satellite is used for receiving satellite signals, if receiving satellite signals in the L frequency band, the target receiving and transmitting link determined by the electronic equipment is a second receiving link, if receiving satellite signals in the S frequency band, the target receiving and transmitting link determined by the electronic equipment is a first receiving link, when the space-borne satellite is used for transmitting satellite signals, the target receiving and transmitting link determined by the electronic equipment is a second transmitting link, and when the space-borne satellite is used for receiving satellite signals, the target receiving and transmitting link determined by the electronic equipment is a third receiving link.

After the target transceiving link is determined, a control instruction is generated, wherein the control instruction carries the target transceiving link. In the transceiver and the signal processing chip for transmitting the control instruction, when the signal processing chip includes a baseband chip and a radio frequency chip, the control instruction is transmitted to the transceiver and the radio frequency chip.

In order to achieve control of the enabling terminals of the first and second operational amplifiers, in an alternative embodiment, the method may further comprise:

When the radio frequency front end module is powered on, an initialization signal is sent to the signal processing chip so as to inhibit enabling of the first operational amplifier and the second operational amplifier.

It can be appreciated that when the rf front-end module is powered on, the rf front-end module needs to be initialized, and then an initialization signal is sent to the signal processing chip, so that the signal processing chip sends disable enable signals to enable ends of the first operational amplifier and the second operational amplifier to disable enabling of the first operational amplifier and the second operational amplifier.

Therefore, after the radio frequency front end module is electrified, the first operational amplifier and the second operational amplifier are disabled, so that the first operational amplifier and the second operational amplifier are disabled, and the power consumption of the radio frequency front end module can be reduced.

In addition, in order to further control the switch component to enable the target transceiving link to transceive the satellite signal, in an alternative embodiment, S902 may include:

when the target receiving-transmitting link is the first receiving link, a control instruction is sent to the transceiver and the signal processing chip, wherein the control instruction is used for: the transceiver controls the switch assembly to enable the first receiving link to receive satellite signals;

when the target receiving-transmitting link is the second receiving link, a control instruction is sent to the transceiver and the signal processing chip, wherein the control instruction is used for: the transceiver controls the switch assembly to enable the second receiving link to receive satellite signals;

When the target receiving-transmitting link is the first transmitting link, a control instruction is sent to the transceiver and the signal processing chip, wherein the control instruction is used for: the signal processing chip enables the first operational amplifier, and the transceiver controls the switch assembly to enable the first transmission link to transmit satellite signals;

when the target receiving-transmitting link is the third receiving link, a control instruction is sent to the transceiver and the signal processing chip, wherein the control instruction is used for: the transceiver controls the switch assembly to enable the third receiving link to receive satellite signals;

When the target receiving-transmitting link is the second transmitting link, a control instruction is sent to the transceiver and the signal processing chip, wherein the control instruction is used for: the signal processing chip enables the second operational amplifier, and the transceiver controls the switch assembly to enable the second transmitting link to transmit satellite signals.

It will be appreciated that after the target transceiving link is determined, the control instructions are received by the transceiver and the signal processing chip by sending the control instructions to the transceiver and the signal processing chip.

For the first receiving link, the second receiving link and the third receiving link, only the input end of the transceiver control switch assembly is needed, so that the first receiving link, the second receiving link and the third receiving link can receive satellite signals.

For the first transmit chain and the second transmit chain, in addition to the input terminal of the transceiver control switch assembly, the signal processing chip is required to enable the first operational amplifier so that the first transmit chain transmits satellite signals, and the signal processing chip is required to enable the second operational amplifier so that the second transmit chain transmits satellite signals.
