D This DCS module provides excellent linearity and efficiency in a w versatile low-cost surface mount package.
The PFM18030SM includes two stages Package Type: Surface Mount wof amplification, along with internal sense FETs that are on the same silicon die as the RF devices.
These thermally coupled sense FETs simplify the task of bias temperature compensation of the overall amplifier.
The module includes RF input, interstage, and output matching elements.
The source and load impedances required for optimum operation of the module are much higher (and simpler to realize) than for unmatched Si LDMOS transistors of similar performance.
The surface mount package base is typically soldered to a conventional PCB pad with an array of via holes for grounding and thermal sinking of the module.
Optimized internal construction supports low FET channel temperature for reliable operation.
