LS4416 N-CHANNEL JFET Linear Systems replaces discontinued Siliconix 2N4416 The LS4416 is a N-Channel high frequency JFET amplifier The LS4416 N-channel JFET is designed to provide high-performance amplification at high frequencies. The hermetically sealed TO-72 package is well suited for military applications. The TO-92 package provides a lower cost commercial option LS4416 Benefits: Wideband High Gain Very High System Sensitivity High Quality of Amplification High-Speed Switching Capability High Low-Level Signal Amplification 10dB (min) 4dB (max) Maximum Temperatures Storage Temperature Operating Junction Temperature Maximum Power Dissipation Continuous Power Dissipation MAXIMUM CURRENT Gate Current (Note 1) MAXIMUM VOLTAGES Gate to Drain or Gate to Source LS4416 Applications: FEATURES DIRECT REPLACEMENT FOR SILICONIX 2N4416 EXCEPTIONAL GAIN (400 MHz) VERY LOW NOISE FIGURE (400 MHz) VERY LOW DISTORTION HIGH AC/DC SWITCH OFF‐ISOLATION ABSOLUTE MAXIMUM RATINGS @ 25°C (unless otherwise noted) High-Frequency Amplifier / Mixer Oscillator Sample-and-Hold Very Low Capacitance Switches ‐65°C to +200°C ‐55°C to +135°C 300mW 10mA ‐30V LS4416 ELECTRICAL CHARACTERISTICS @ 25°C (unless otherwise noted) SYMBOL CHARACTERISTIC MIN TYP.
