Is it posible to design a 90 degree phase shifter using a single PIN diode and microstrip lines?? :!: :idea: :?:
Dear all, could you give me some advice or paper about 8 bit digital phase shifter.Frequce is 2 to 6 it can be maked by microstrip? Thanks very much for your view and help.
Dear all I want to design a wide band phase shifter (90GHz-220GHz) based on microstrip technology (Niobium superconductor) Schiffman phase shifters seems to be good for that Could anyone give me some technical notes concerning such things or if I am wrong, suggest another technology. Thank you
Refer to Microwave Engineering by David M.Pozar 3rd edition. This book gives comprehensive analysis about designing microwave microstrip circuits. Methods for designing phase shifter is available in this book. or else refer to Microwave circuits by Balanis
thanks, but I need a design paper not a product. I prefer with microstrip, no MEMS
Hello, I found some simple examples of the microstripe phase shifters at the CST and IE3D examples see attach. Please could you know, where was this structures publicated or where can I find some information about this microwave circuit ? Somethink like basic princip or How-to design and calculation ? Thanks for information
Hello, everybody! I model a planar ferrite phase shifter with a meander-like microstrip like this one - Experiment has shown that losses are equal 2dB. Is it possible to have losses about 1dB? Any help or paper is appreciated.
Because the L and C values will be very small at high frequencies, the variation of induction and capacitance due to temperature or other factors, will be translated in a phase change. LC phase shifters are recommended for relative low frequencies. For high frequencies better is to use microstrip lines.
You can use a mmic phase shifter chip, such as The trick will be to find one off-the-shelf for your 1-2 ghz frequency band. You can design your own phase shifer, using time delay length of microstrip line that get switched in/out. The benefit of this approach is that you can
hi i want to design switched line phase shifter for 8X8 microstrip patch array antenna at 35GHZ using transmission lines. Can anybody give idea about how to design it in ADS ?
okay, thanks for the answer i'll approach our local PCB manufacturer:smile: also if i may ask what the best methods to realizing the lumped element filter into microstrip filter for 4-bit LPF/HPF phase shifter?? i propose a stepped impedance methods to realizing the filter, but the result is not quite good. o yeah, the substrate, (...)
Dear all I am communication engineer in Uk .. I'm working in the following project : " Investigation of Adaptive Microwave Communication System Using Novel Planar Antennas ". The type of antenna : rectangular microstrip antenna Frequency : 5 GHz The project has to achieve this type of antenna with some applications as follows :- 1
Hi everybody I am searching for informations concerning wideband analog phase shifters(continuous phase shift). I am trying to design such thing in microstrip technology. I am also searching for more informations concerning shiffmann phase shifters. Do you know where I can find these (...)
Hello , How can I design a phase shifter in MIcrowave Office. I am to use RT/Duroid as the dielectric...could anyone help with leads of the schematics....i knowi am to use 2 SPDT's at either ends of the transmission is to operate at 5GHz and have a phase shift of 45 degrees.
Is there a topology for design of a (2~3 octave)? I prefer in microstrip technology 8~18 GHz
Hmm, yeah, not sure what I was smoking. Anyway, it was confusing to me that your structure is *below* the ground plane not above it. Since the copper forms a nearly perfect conductor, there is no need for an air box above it. You can delete all that air and instead put it below the microstrip, where there is only a little bit of air now and more
Hi, I need help in shortening the length of the microstrip line. Supposingly I need to have a microstrip line which give me a 8ns of delay in the 300MHz frequency. Then I will need to have a very long microstrip line to obtain that. Any ways or methods that I could use to shorten the length while maintaining the 8ns delay? (...)
Hello !! Actually m designing switched line phase shifter and switching using PIN diodes(series-shunt config) on 50Ω microstrip, with substrate ε=2.2, h=31mils. For providing Bias to PIN diodes i have used Radial stub and λ/4 high impedance line.The biasing is such that At the series shunt configuration when series diode (...)
Heya rf1008, As you've found, lengths of transmission line work fine as phase shifters for single frequencies but are useless for broadband operation. For wider bandwidths (on the cheap - i.e. without using turnkey solutions such as ), I've had a great deal of success with combinations of f
In my design, there is a RF switch, but I donot want to use a balun. So I must use some lump components or microstrip line to act as a balun. But I donot know how to design the components or microstrip line 's value . For example, , on page 26 and 27. The input port is differential with Z=2-j4, only f

in front of LNA(between LNA and ANT) we need to use low loss filters,and LC and microstrip filters have high loss ,so we should use other types like as HELICAL filters or CAVITY filter ,... these filters is mechanical and not electronic in construction ,but I can not find any good design information on them,plz send info for us if u have good links
hi can any one help me in getting the matlab code for microstrip delay transmission line phase shifter with 3 bits or T junction power divider
hello every1, I am working on X-band analog phase shifter design, need some help in LANGE coupler design (using ADS for simulations). I want to design above coupler using microstrip for material having dielectric constant=2.94, i m not able to compute w/h, s/h. Also how to consider laminate (dielectric constant value).
Hi i want to design a phase shifter in microstrip and i want to use macomtech MASWSS0192 SPDT switch what i want to ask is how can i modeling the SPDT switch in ADS?? here's the datasheet88309
Hi I want to design a phase shifter using microstrip that worked at 2.4 GHz and using MASWSS0136 as switch what i want to ask is how to design a bias network for MASWSS0136 switch??? so far what i've been searching is to use the λ/4 bias tee or radial stub but i guess the bias tee and radial stub is used to biasing LNA or HPA (...)
I can't understand, S-parameters affect somehow 180deg phase line between active devices of push-push oscillator? There are few S parameters, wich of them must be taken into account, or maybe none of them? In case of common resonator, if resonator itself is a 180 deg phase, i think lines from resonator to both oscillators can be any lenght, but
