and 8-Pin MSOP (LTC4401-2) Packages

The LTC

4401-1 is a SOT-23 RF power controller for slow

turn-on RF power amplifiers operating in the 300MHz to

2.7GHz range. The loop bandwidth is set at 250kHz

to improve frequency stability when controlling slow

turn-on RF power amplifiers such as the Conexant

CX77301/CX77302, CX77304, CX77314, Anadigics

AWT6107 and the RF Micro Devices RF3160.

RF power is controlled by driving the RF amplifier power

control pins and sensing the resultant RF output power

via a directional coupler. The RF sense 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 tempera-

ture 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 (LTC4401-2) is also

available in an 8-pin MSOP package.
