microwave PIN and schottky diodes

i need to buy some PIN and Schottky diode operates in C band up to 8 Ghz ,
i have check avago but the diodes are very expensive

is there any anothers in the market

thanks in advance

Hi

You can check out Microsemi or Skyworks

M/A-COM also produce PIN diode. However at this so high frequency band, I wonder the die is your only choice and it couldn't be cheap.

actually i don't have facilties to solder the die or wire bond it , but i need a packaged diode to be able to use it

i will them in Mixer, power detector applications in this band

For the mixer see Infineon's BAT14 and BAT15 series.

great rfmw ,
i have seen the diodes , and got the spice modes for the website , but i don't know in which format
do u know ? , or did u use the nonlinear models for these diodes before

Infineon doesn't provide ready-to-use spice models. They provide chip SPICE model and package model separately. You have to manually join the models together in a single model for the device.

But the Ansoft designer already has the model ready to go and ADS should have it too no?


I haven't tried the BAT14 or BAT15 series models myself, but many others. You just have to be careful joining the package and chip model together to make a sub_ckt...

Hope you have success with it.

yeah i have noticed that they provide them separatly , i will try yo join them , and regerated the data and compare it with S paramters

Exactly so!
