Advantage of HJT over BJT is that it has: Correct Answer high frequency of operation

The gain of BJT reduces with the increase in the operating frequency. This problem is overcome in HJT which gives sustained gain even at frequencies of about 100 GHz. They are also suitable for application in low power circuits.
