“While traditional base stations provide four to eight transmit and receive channels, 5G massive MIMO infrastructure designs typically call for 32 or 64 transmit and receive channels,” according to the company.

BTS6302U pre-driver has an integrated balun

The amplifier is unconditionally stable and has an ACLR (adjacent channel leakage ratio) of -43dBc.

Running for 5V it consumes 68mA quiescent.

Each channel of the BTS7203U (right) has a switch for a 50Ω terminating resistor for handling transmit signals up to 37dBm (9dB PAPR). Dissipation is 170mW per channel.

The amplifier is matched to 50Ω and integrates harmonic and out-of-band filtering.
