Enhancement--Mode Lateral MOSFETs
These RF power devices are designed for pulse applications operating at
frequencies from 900 to 1215 MHz. The devices are suitable for use in pulse
applications with large duty cycles and long pulses and are ideal for use in high
power military and commercial L--Band radar applications such as IFF and
DME/TACAN.
