Hi,

 

       Iam designing 700MHz Oscillator using PIN diode concept.For this iam using 100MHz AT-CUT crystal oscillator ouput and passed to PIN diode and iam using BPF followed by Amplifier.I can able to get 700MHz output but iam getting ouput level varaiation of ± 2 dB over -40 to +85°C.Is there any detector or AGC IC to control o/p level to ±0.5dB over -40 to 85°C.Pls help me to solve this problem.

 

Regards,

Varaprasad.
