MC33170 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.
