Richardson RFPD Inc. announces immediate availability and full design support capabilities for a range of RF MOSFET replacement partsfrom STMicroelectronics (ST). ST's legacy RF MOSFET power transistors represent pin-for-pin replacements for several discontinued products from NXP, including the BLF175, BLF177 and BLF278.
ST's replacement parts provide equivalent performance at a reduced cost. Key features of the devices include:

In addition to maintaining its legacy products, ST continues to develop new products to address high performance designs. For customers looking for higher performance without the necessity of a complete circuit redesign, ST offers several new devices for broadcast, MRI, RF plasma generator, and laser driver applications. The SD49xx series feature 20:1 VSWR. STAC packaged devices include characterization under pulsed conditions. Key features of these devices include:
