Description:
...turn-on RF power amplifiers operating in the 300MHz to2.7GHz range. Examples include the Hitachi PF08109B,PF08122B, PF08123B, PF08107B and RF Micro DevicesRF3108. For slow turn-on RF power amplifiers refer to the... ...RF power is controlled by driving the RF amplifier powercontrol pin and sensing the resultant RF output power viaa directional coupler or capacitive tap. The RF inputvoltage is peak detected using an on-chip Schottky diode.... ...ceramic decoupling capacitors placed close to the RFpower amp supply pins. The range of decoupling capacitorvalues is typically 1nF to 3.3m F.5) Poor layout techniques associated with the RF coupling...
