any one having the book
Tri T. Ha, "Solid-State Microwave Amplifier Design," John Wiley & Son, 1981
please send a post to me if any one having this book.
its good book for designing amplifiers
hi ...... iam fresher candidate who is doing MTECH in iit of specialisation RF and micorwave ...... i want to choose a career as a rf design engineer
can anyone tell me where are the jobs for freshers as a design engineer in india
plzzzzz help
can u plz send the nadeem paper for me
bcoz i have one basic question for filter why the resonator impedance is high when we go for narrow band filters and why the resonator impedance is low when we go for wide band filter????????????
Re: return loss in filters - feed line and resonator mismatc
hi frnd is it necessary to place a lumped capacitor to combline filter when we are implementing in microstrip......( i have read in some text book that when we are implementing in strip line configuration.......then we have to place a...
Re: return loss in filters - feed line and resonator mismatc
hi frnd u said to add quarter wave transformer between tapline feed and first resonator ......some people are saying not to use any quarter wave transformer ............so what to do???????so what to do
plz help
hi frnds i want to design a combline bandpass filter using tapped line input..... the problem coming here is the location of tappedline on the first resonator...from my specs my external quality factor is around 182... by parameter extraction for determination of external quality...
Re: return loss in filters - feed line and resonator mismatc
u said that at tap point location there should be matching of 50 ohm and resonator impedance .. how can i locate the tap point on resonator that the impedance is 50 ohm ....actually by parameter extraction technique (i take 2...
Re: return loss in filters - feed line and resonator mismatc
when there is a mismatch then what i have to do??? whether i should put any impedance inverter to match 50 ohm and high impedance line
plz help in ADS
hi frnds iam designing a combline bandpass filter using ADS ..what is the characteristic impedance of the resonator????whether it is 50 ohm or greater than 50 ohm(why???)........i have to short circuit the resonators in layout window using via hole grounding .........plz explain...
I have designed a microstrip layout of power amplifier at 2.4 GHz. The input and output matching sections have been designed in microstrip.
But my DC bias network is containing lumped components - inductors and capacitors.
I want to replace these inductors and capacitors with microstrip lines so...
hi frnds iam designing a combline filter in the layout window of momentum(ADS) iam getting problem how to define a via hole grounding and how to place a via hole ground on to the resonators(since my resonators should be short circuited to ground) whether i have to modify the subrate layers and...
when we design a bandpass filter either interdigital or combline or hairpin using tapped line feed input...since the tapped feed is 50 ohm and resonator impedance is greater than 50 ohm so there is a mismatch in impedance .....whether we can make the resonator impedance also equal to 50 ohm or...
hi frnds iam desinging a combline bandpass filter......i want to know the spacing between the resonators and the location of tapped feed line.....
for extracting coupling coefficients between a pair of resonators using EM simulation how should be the resonators be placed( like they should be...
abt filters
when we talk abt filters we talk only abt insertion loss but we dont talk abt return loss why??????
when iam designing a combline or interdigital using tapped line input i directly give feed line( 50 ohm) to resonator which is having an impedance of greater than 50 ohm ...so there...
