Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may support multi-subscriber identity module (SIM) operation in dual SIM dual active (DSDA) deployments. In some aspects, the UE may receive, via an antenna of the UE, a first signal associated with a first network subscription on a first receive path of the antenna and a second signal associated with a second network subscription on a second receive path of the antenna. The UE may determine a signal strength for each of the first signal and the second signal, determine a first gain for the first receive path and a gain for a low noise amplifier (LNA) coupled with the antenna based on the signal strength of the first signal, and determine a gain for the second receive path based on the signal strength of the second signal and the gain of the LNA.
