Despite recent improvements in the performance of RF LDMOS field-effect transistors (FETs), temperature drift and aging continue to affect the efficiency and linearization of power amplifiers using ...
Dallas Semiconductor introduced the DS1870, the industry's first complete LDMOS power-amp biasing and monitoring solution. The device optimally biases two LDMOS power amps over temperature and drain ...
In a simplified schematic from its datasheet, Linear Technology's LTC6268 (and 6269 dual) provide no evidence of "secret sauce." Rather, it shows a combination of semiconductor design and process ...
