The CC1190 PA is designed to work in compression (class AB), and the best efficiency is reached when a strong input signal is applied. The output power can be reduced by setting the pin HGM low. If a reduced maximum output power is wanted, the impedance seen by the PA should be increased, thus increasing the PA efficiency by changing the output matching network. Input Levels on Control Pins The three digital control pins (PA_EN, LNA_EN, HGM) have built-in level-shifting functionality, meaning that if CC1190 is operating from a 3.6 V supply voltage, the control pins will still sense 1.6 - 1.8 V signals as logical '1'. An example of the above is that PA_EN is connected directly to the PA_EN pin on CC110x, but the global supply voltage is 3.6 V. The PA_EN pin on CC110x will switch between 0 V (RX) and 1.8 V (TX), and this is still a high enough voltage to control the operating mode of CC1190. However, the input voltages should not have logical '1' level that is higher than the supply. Connecting CC1190 to a CC102X Device Table 2.
