RF Amplifier Companion Chip

for Dual-Band Cellular

Subscriber Terminal

The MC33170 is a complete solution for drain modulated

dual–band GSM 900MHz and DCS–1800MHz Power Amplifiers.

Thanks to its internal decoder, the MC33170 drastically simplifies the

interface between the PAs and the baseband logic section, providing

an immediate gain in part count but also in occupied copper area. The

device is also ready for 1V platforms since it accepts logic high control

signals down to 900mV@25°C.

A priority management system ensures the negative is present

before authorizing the power modulation, giving the necessary

ruggedness to the final design. This function can easily be disabled for

PAs not requiring a negative bias.

CASE 948G

The device is able to directly drive an external P or N–channel with

the possibility to linearize the overall response via the internal

high–performance control amplifier and easily implement system

gain.

Finally, an LDO delivers a stable voltage, usable for external biasing

purposes.
