| IP개요 | This paper presents a bi-directional power amplifier and low noise amplifier (PA-LNA) that operates on the upper-mid band for 6G communication, exhibiting high output power and low noise figure. The proposed PA-LNA supports bi-directional operation, unlike the existing PA-LNA that utilizes cross-coupling-capacitor neutralization to reduce insertion loss. In the proposed PA-LNA structure, a differential structure and cross-coupling capacitors are utilized to minimize the gain loss of PA and LNA caused by insertion loss. To support bi-directional operation, the input and output matching network of PA and LNA must be shared in the proposed PA-LNA. To achieve this, the proposed PALNA utilizes switches in the input and output matching networks of the PA-LNA to configure the output matching of the PA and the input matching of the LNA. From a 6G communication perspective, this PA-LNA enables chip size reduction by supporting the bi-directional operation and enables a combined design with other beamforming elements. |
