Assignee: SAMSUNG ELECTRONICS CO., LTD.
Field: Telecommunications (Electrical engineering)
Classification: CPC H | IPC H

Claim 14:
15. An electronic device comprising:
a first printed circuit board (PCB);
a first antenna element and a second antenna element disposed on the first PCB, wherein the first antenna element and the second antenna element form an antenna array to transmit and/or receive a mmWave frequency band;
a second PCB;
a plurality of power amplifiers (PAs) disposed on the second PCB and electrically connected to the antenna array;
a plurality of low noise amplifiers (LNAs) disposed on the second PCB and electrically connected to the antenna array, wherein a number of the plurality of LNAs electrically connected to the antenna array is greater than a number of the plurality of PAs electrically connected to the antenna array;
a first transmission-reception circuit disposed on the second PCB and electrically connected to the first antenna element, wherein the first transmission-reception circuit includes a first PA among the first plurality of PAs, and a first LNA among the first plurality of LNAs, wherein the first PA forms a portion of a transmission path, and wherein the first LNA forms a portion of a first reception path;
a first reception circuit disposed on the second PCB, wherein the first reception circuit does not include a PA, and includes a second LNA among the first plurality of LNAs, and wherein the second LNA forms a portion of a second reception path; and
a radio frequency integrated circuit (RFIC) disposed on the second PCB and including a mixer,
wherein the mixer is electrically connected to the first antenna element via the first transmission-reception circuit and the second antenna element via the first reception circuit such that the mixer receives RF signals from both the first antenna element and the second antenna element.
