This device has been transferred from Ampleon to Rochester Electronics.
Avionics LDMOS transistor
Silicon N-channel enhancement mode lateral D-MOS transistor encapsulated in a 2-lead SOT502A flange package with a ceramic cap. The common source is connected to the mounting flange.
Features and benefits
- High power gain
- Easy power control
- Excellent ruggedness
- Source on mounting base eliminates DC isolators, reducing inductance.
Applications
- Avionics transmitter applications in the 960 MHz to 1215 MHz frequency range
- Mode-S, TCAS and JTIDS, DME or TACAN
