The application shown in Figure 8-1 demonstrates how to toggle between the DAC output and a low signal voltage for control of a power amplifier. A device such as the TMUX6234 that supports multiple supply voltage combinations allows the system designer to use a single switch across platforms with different power amplifier topologies such as GaN or LDMOS implementations. Using a multi-channel switch like the TMUX6234 allows the system to improve density by implementing a smaller solution size. Multiple channels of the TMUX6234 can be utilized to switch additional stages of a single power amplifier channel. Or multiple channel switches can be used on different power amplifier stages in high channel count communicaitons equipment such as a 32 transmist (TX), 32 receive (RX) active antenna system mMIMIO (AAS). Each channel of the TMUX6234 has independent control signals allowing for overal system flexibility. The DAC output is utilized to bias the gate of the power amplifier and can be disconnected from the circuit using the select pins of the switch or the golbal enable pin. The TMUX6234 can support 1.8 V logic signals on the control input, allowing the device to interface with low logic controls of an FPGA or MCU. All inputs to the switch must fall within the recommend operating conditions of the TMUX6234 including signal range and continuous current. For this design with a positive supply of 8 V on V_DD, and negative supply of -12 V on V_SS, the signal range can be 8 V to -12 V. The maximum continuous current (I_DC) is captured in the Recommended Operating Conditions table for a range of supply voltage cases.
