Q. If the RMS peak current in an IMPATT diode is 700 mA and if DC input power is 6 watt, with the load resistance being equal to

(A) 10.1 %
(B) 10.21 %
(C) 12 %
(D) 15.2 %
Correct : Option (B)

Explanation: 
 efficiency of impatt diode is defined as the ratio of output rms power to the input dc power. calculating the rms output power from the given rms current and substituting in the equation of efficiency, the efficiency is 10.21%.
