Hi Guys,
Need some help on ADS simulation using FFT function. I need some guide to convert the RF signal to FFT in ADS. I wanted to extract signal from osciloscope and get the ADS to convert time base signal to FFT. Can any one help on this
Hi Guys,
Wanted some advice on HSMP389C pin diode which i saw in receive design. Its was used as limiter, placed at the input of LNA. How can i calculate the maximum power handling of the limiter in that circuit before its damage due to high power transmited to receive path. I read thru the data...
How can i simulate assymetrical strip line in ADS assume the stripline runs in layer 2 and shielded by top and layer 3 with different substrate thickness.
Hi Guys
Im curious to learn how does behavior model for RFPA is extracted from the PA. Currently im having tough time getting the simulation models for RFPA. Would appreciate if any one could suggest a way to extract the behavior model for RFPA
Thanks
Hi Guys,
Im working RFPA development for UHF 2 design using MRF1570 freescale part. When conducting VSWR 3:1 load pull to check the stability i found for some angle there is Half Carrier Spurs. Spurs with delta frequency of 1/2MHz from un-modulated carrier. But the spurs reduced once bias...
RF power amp analysis
Hi guys
i need some material on multistage amplifier stability analysis. Is there any paper or guide in analyzing the stability for multistage rf power amp.
thanks

HI guys,
I would like know who could i simulate a RF detector in ADS. here is my problem, i need to simulate a diode which i have the spice model for it. I need to plot rfin vs voltage detected at the detector end. Any one has any example tht can share with me that would be great.
thanks

calculation for hairpin filter
Hi Guys,
I have read thru this paper as im currently working on Hairpin filters. I notice there is passband ripple occurs for this conventional hairpin design presented on this paper. Im suprise since the filter was contructred using butterworth configuration...
Filter Doubts
Hi guys
im kind of new to filter design would like to know futher information on filter design.
i wanted to know what does it mean by filter null point? thanks guys
