VHF push-pull power MOS transistor
BLF368
FEATURES
High power gain
Easy power control
Good thermal stability
Gold metallization ensures
excellent reliability.
DESCRIPTION
Dual push-pull silicon N-channel
enhancement mode vertical D-MOS
transistor, designed for broadcast
transmitter applications in the VHF
frequency range.
The transistor is encapsulated in a
4-lead SOT262A1 balanced flange
package, with two ceramic caps. The
mounting flange provides the
common source connection for the
transistors.

QUICK REFERENCE DATA
RF performance at Th =25 °C in a push-pull common source test circuit.
Note
1. Assuming a 3rd order amplitude transfer characteristic, 1 dB gain compression corresponds with 30% synchronized
input/25% synchronized output compression in television service (negative modulation, CCIR system).
