National LMV242 Data Sheet
Summary
This advanced PA controller is engineered for sophisticated RF transmit power control in quad-band GSM/GPRS mobile devices. It manages the critical output stage using two selectable drivers, while integrating essential functions like a 50 dB RF detector and an adjustable ramp filter. The unit supports multiple PA technologies (InGaP, HBT, bipolar) on a single supply voltage and features low-power shutdown modes. Ideal for electronics designers building small footprint, high-efficiency communication modules requiring precise power management and reliable performance across different mobile standards.

Frequently Asked Questions
What voltage range must be used to power the LMV242?
Its operating supply voltage must be between 2.6V and 5.5V.
How are the two output drivers (OUT1 and OUT2) selected?
The 'Band Select' (BS) digital input enables either OUT1 or OUT2 based on its signal level.
What happens to the outputs when the device enters shutdown mode?
When TX_EN is Low, the device enters low power consumption shutdown, and both outputs are pulled low to minimum output voltage.
How can individual PA characteristics be accommodated by the user?
Individual PA characteristics are accommodated using a user-selectable external RC combination.
