Palomar ERF-9530

The Palomar ERF-9530 is an RF Power MOSFET transistor designed for high-power amateur and CB radio applications. It is rated for 100 watts PEP (peak envelope power) and serves as an upgrade replacement for the earlier ERF-7530 model.
Specifications
Type: RF Power MOSFET transistor.
Power Rating: Conservatively rated at 100 watts PEP.
Application: Designed for mobile HF band two-way radio and amplifier applications, commonly used in high-powered 10 & 11 meter radios.
Features: Features new silicon wafer designs for improved durability and ruggedness against high heat, high VSWR (Voltage Standing Wave Ratio), high voltages, and current levels.
Package Type: Comes in a TO-3PN insulated package for mounting.
Replacement For: A direct “drop-in” replacement and upgrade for the Palomar ERF-7530 transistor.
Installation: Requires proper technical skills, tools, and soldering equipment for installation; not a simple plug-and-play component.
Expert and User Opinions
Durability and Quality: Palomar’s new wafer technology creates a new level of ruggedness, enabling the transistor to withstand adverse conditions.
Performance: The ERF-9530 is used as an upgrade in older equipment (like the Palomar HD250 Fet amplifier) to achieve more output power, with some configurations pushing over 225 watts output with appropriate input drive.
