8.2.1 Power Amplifier Gate Driver
One application of the TMUX6219 is for input control of a power amplifier gate driver. Utilizing a switch allows a system to control when the DAC is connected to the power amplifier and can stop biasing the power amplifier by switching the gate to VSS. The wide dual supply range of ±4.5V to ±18V allows the switch to work with GaN power amplifiers, and the wide single supply range 4.5V to 36V works well with LDMOS power amplifiers.
Figure 8-1 shows the TMUX6219 configured for control of the power amplifier gate driver in GaN application.
