Controlling the Output Power from CC2590

The output power of CC2590 is controlled by controlling the input power. The CC2590 PA is designed to work in

compression (class AB), and the best efficiency is reached when a strong input signal is applied.

Input Levels on Control Pins

The four digital control pins (PAEN, EN, HGM, RXTX) have built-in level-shifting functionality, meaning that if the

CC2590 is operating from a 3.6-V supply voltage, the control pins will still sense 1.6-V - 1.8-V signals as logical

‘1’.

An example of the above would be that RXTX is connected directly to the RXTX pin on CC24xx, but the global

supply voltage is 3.6-V. The RXTX pin on CC24xx will switch between 0-V (RX) and 1.8-V(TX), which is still a

high enough voltage to control the mode of CC2590.

The input voltages should however not have logical ‘1’ level that is higher than the supply.
