Ruggedized LDMOS White Paper ART (Advanced Rugged Technology) White Paper Ampleon’s advancements with ruggedized Si LDMOS transistors of up to 2 kW of RF Power for 1 through 400 MHz Tom Dekker, Director Marketing, Multi-Market AMEC Overview Ampleon recently released a series of rugged transistors, engineered specifically for the industrial, scientific and medical applications which offer robust VSWR ruggedness withstand while delivering the best in terms of RF power, gain and efficiency. We named this series “ART”, short for “Advanced Rugged Transistor”. ART’s novel Silicon LDMOS node was engineered to obtain a high drain-source breakdown while maintaining a compelling low output capacitance to allow for a rugged transistor with high transconductance in the frequency range from HF through UHF. The ART series has two versions: ART1K6 (50 V V DS / 177 V V DS minimum breakdown) and ART2K0 (65 V V DS / 200 V V DS minimum breakdown range). The high VDS breakdown offers the threshold for VSWR ruggedness features during 65:1 withstand conditions. Further, the low output capacitances allow for frequency ranges of up to 450 MHz with high gain and efficiency. The chart below provides a comparison of features to our popular BLF188XR (current generation in high volume production) and provides some perspective on comparison to the competitive landscape of devices. The ART1K6 and ART2K0 are offered in industry standard packages, either air-cavity ceramic or over-mold plastic packages suitable for attach direct to an amplifier heatsink or copper-coin planar with PCB with gull-winged packages. Class-E designs are enabled at 50 V for ART2K0. Device is within all operating limits of up to 6dB compression. Testing underway to extend Class E operation at 50 V to 10 dB compression. All ART Family devices have an internal stability network contained in the die. This network results in close to unconditional small signal stability at low frequency without the need for any external circuitry.
