New 4G phones have higher data upload requirements, such as “real-time,” on-and-off use of applications, which require higher RF power amplifier output levels to support LTE operation, even at lower ...
To help get more life out of a battery, Texas Instruments introduced an efficient envelope tracking power supply solution to support 3G and 4G LTE multi-mode, multi-band RF power amplifiers used in ...
3G finally percolates the cell-phone arena with UMTS, cdma2000, and TD-SCDMA, but companies gear up for 4G products. Sure, almost everyone is inextricably tied to a cell phone these days. But how much ...
The LM3253 is a DC-DC converter optimized for powering multi-mode 2G/3G/4G RF power amplifiers (PAs) from a single Lithium-Ion cell. The LM3253 steps down an input voltage from 2.7V to 5.5V to a ...
