GSM PA Drain Controller for Dual Band Cellular Subscriber Terminal
MC33170
RF Amplifier Companion Chip
for Dual-Band Cellular
Subscriber T erminal
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.
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. 1V platform compatible: ON voltage = 900mV, OFF voltage =
300mV max Priority management system prevents power modulation before
negative bias establishes High performance 4.5MHz gain–bandwidth product operational
amplifier Drives N or P–channel MOSFET 2.5V low–noise LDO Idle mode input for very low power consumption (standby mode)
