required help for designing Oscillator at 5.8GHz

[Abhishekabs]

hi friends
I am designing oscillator at frequencey 5.8GHz
I am using GaAsFET transistor(low noise) as an active device.
I want do design oscillator with microstrip resonator
Can any one tell me how oscillator is designed at this frequency??
I want to swith it on for duration of 1ns.( Its Q is low)
I dont have any references
thanks

for good oscillator start , try

pozar book , and chapter 5 of gonzalez book

also , nonlinear microwave and RF circuit design of steven mass is good

about how it is done , u use the microstrip as a feedback element to make the amplifier is unstable , and then , design the resonator for this frequency

what is ur transistor part number

[Abhishekabs]

Transistor is NE 3210S01 ( low noise FET)

frist u go www.cel.com ,and get the ads design kit , which includel the nonlinear models of the transistor , and begin the design process

I dont have ADS currently
please tell me other solution

I dont have ADS currently
please tell me other solution

What simulator software are you using?

 

[khouly]

u can use MWO , or whcih CAD package u will use

[Abhishekabs]

I will use MWO
can u suggest me any IEEE or any other publication paper
which describes method of designing high frequency oscillator using GaASFET
with example, so that I can study various methods
Thanks

check the books

microwave solid state circuits "indr bahal"
microwave circuit design using linear and nonlinear techniques "Rohde"

Hi,

The best book for RF circuits Designing is RF Circuit design by Ludwig & Brethcko You can search it on EDA Board Books.

Thanx
