At 50 V V\u003csub\u003eDS\u003c\/sub\u003e, the part is typically specified for 200 W of RF output at 30 MHz, 150 W at 100 MHz, and 100 W at 175 MHz — a familiar workhorse in 100–200 W amateur, broadcast, and industrial RF amplifier designs. KOEED lists the SD2942 as a related semiconductor category alongside our core Allen-Bradley, Siemens, Mitsubishi, Omron, Fanuc, Schneider, Yaskawa, Panasonic, and KEYENCE automation lines, because the same plant-floor engineering teams that spec PLC CPUs also maintain the RF heating, plasma, and broadcast subsystems the SD2942 drives.\n\u003c\/p\u003e\n\n\u003c!-- ============ H2 1: Key Technical Specifications \/ Overview ============ --\u003e\n\u003ch2 style=\"font-family:Arial, Helvetica, sans-serif; color:#111111; font-size:22px; line-height:30px; margin:32px 0 16px 0;\"\u003e\n  1.

The published headline figures — 200 W at 30 MHz, 150 W at 100 MHz, 100 W at 175 MHz — describe typical push-pull common-source operation; production broadcast and amateur users typically de-rate to a 150 W class for long key-down reliability.
