SD1477
SD1477 is RF & MICROWAVE TRANSISTORS manufactured by SGS-Thomson.
- Part of the SD1477-SGS comparator family.
- Part of the SD1477-SGS comparator family.
DESCRIPTION
The SD1477 is a 12.5 V Class C epitaxial silicon NPN planar transistor designed primarily for VHF FM munications. This device utilizes diffused emitter resistors to withstand extremely high VSWR under rated operating conditions, and is internally input matched to optimize power gain and efficiency over the 136
- 175 MHz band.
