RFMW announces design and sales support for a high-power transistor from Ampleon. The BLS9G2731L-400U is a 32 Volt LDMOS power transistor for use in 2700 to 3100 MHz, S-Band radar applications. With 400 W pulsed power capability in class-AB circuits, the BLS9G2731L-400U offers 47% efficiency with up to 13 dB of gain. Capable of withstanding output mismatches of 10:1, the excellent ruggedness and thermal stability of this transistor makes it ideal for mission critical applications. Easy power control (no sequencing), internal matching and flexibility with respect to pulse formats makes LDMOS an economical option to alternate technologies. Also available in an earless package as the BLS9G2731LS-400U.
