Samsung patents circuit design to boost 5G signal strength
Samsung has been granted a patent for a specific electronic circuit used in 5G wireless devices. The design connects two amplifiers in a particular way to strengthen the signal sent and received by the phone or base station.
In the filing’s own words
The present disclosure relates to a 5 th generation (5G) or pre-5G communication system for supporting higher data transmission rates than 4 th generation (4G) communication systems such as long-term evolution (LTE). In a wireless communication system, an apparatus comprises: a first amplifier unit that has a common source structure, includes cross-coupled capacitors, and amplifies an input signal; and a second amplifier unit that has a common gate structure, is connected to the first amplifier unit, and amplifies the signal output from the first amplifier unit, wherein the second amplifier unit includes a first input unit, a second input unit, a third input unit, and a fourth input unit, and two input units among the first input unit, the second input unit, the third input unit, and the fourth input unit may be connected to the first amplifier unit.
What exactly they claim (claim 1)
1. A device in a wireless communication system, the device comprising: a first amplifier configured to amplify an input signal; and a second amplifier connected to the first amplifier and having a common gate structure of amplifying a signal output from the first amplifier, wherein the second amplifier comprises a first input unit, a second input unit, a third input unit, and a fourth input unit, and two input units among the first input unit, the second input unit, the third input unit, and the fourth input unit are connected to the first amplifier.
