Low noise amplifiers with cascode divert switch for carrier aggregation

摘要: Low noise amplifiers (LNAs) supporting carrier aggregation are disclosed. In an exemplary design, apparatus (e.g., a wireless device, integrated circuit, etc.) includes first and second amplifier circuits divert cascode transistor. Each circuit may include gain transistor The is coupled between the output of in circuit. receive input radio frequency (RF) signal including transmissions sent on multiple carriers at different frequencies to device. controlled amplify RF provide (i) one amplified for set operating mode or (ii) two signals sets mode.
