3300-5000 MHz, 34 dB, 1.4 dB NF Airfast® RX Module

AFRX5G372

The AFRX5G372 is an integrated multi-chip module designed for TD-LTE and 5G mMIMO applications. It consists of a T/R switch, a two-stage low noise amplifier and support circuitry to work from a 5 V supply and a 1.8 V logic-level T/R control.

The device has Tx and Rx modes, which are controlled via T/R logic signaling. In Tx mode, internal RF switches direct the signal from the antenna port to an external termination resistor. In Rx mode, internal RF switches direct the signal from the antenna port to internal LNAs. While in Tx mode, the LNA is in idle mode with minimized current consumption.
