Description
RF input to the high band power amplifier. DC blocked inside the module.
Ground.
RF input to the low band power amplifier. DC blocked inside the module.
The voltage on this pin controls the output power by varying the internally regulated collector voltage on the
amplifiers. This is a high bandwidth input so filter considerations for performance must be addressed externally.
Main DC power supply for all circuitry in the module. Traces to this pin will have high current pulses during trans-
mit operation. Proper decoupling and routing to handle this condition should be observed.
Digital Control Signal. Binary logic on VCTL1-4 sets module operating state.
