The PN4416 is a N-Channel high frequency JFET amplifier

PN4416

N-CHANNEL JFET

Linear Systems replaces discontinued Siliconix PN4416

The PN4416

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

PN4416 Applications:

High-Frequency Amplifier / Mixer

Oscillator

Sample-and-Hold

Very Low Capacitance Switches

PN4416 Benefits:

Wideband High Gain

Very High System Sensitivity

High Quality of Amplification

High-Speed Switching Capability

High Low-Level Signal Amplification
