功能描述

The LTC4400-1 is a SOT-23 RF power controller for fast turn-on RF power amplifiers operating in the 300MHz to 2.7GHz range. Examples include the Hitachi PF08109B, PF08122B, PF08123B, PF08107B and RF Micro Devices RF3108. For slow turn-on RF power amplifiers refer to the LTC4401-1/LTC4401-2.

RF power is controlled by driving the RF amplifier power control pin and sensing the resultant RF output power via a directional coupler or capacitive tap. The RF input voltage is peak detected using an on-chip Schottky diode. This detected voltage is compared to the DAC voltage at the PCTL pin to control the output power. The RF power amplifier is protected against high power control pin voltages.

Internal and external offsets are cancelled over temperature by an autozero control loop, allowing accurate low power programming. The shutdown feature disables the part and reduces the supply current to <10µA.

A dual control channel version (LTC4400-2) is also available in an 8-pin MSOP package.
