Is there any alternative for Hittite HMC538LP4E and HMC929LP4E?
Hello Everyone !!! This is my problem : I have this corporate feed neetwork (planar EM) and a simpliest phase shifter (CircuitSimulator): 134859134860 i've exoprted the S matricies of both model in an other project and i've put it in a two general network linked as in the following figure :
Hello EveryOne !!! I'm simulating with ansoft designer V2 circuit simulator, a switched line phase shifter ( a very basical model ).This is the scheme : 134741 the problem is : SPDTs has v1=2V and V2=4V. When SPDTs switch on the upper line (Vctrl < v1 and Vctrl=0) the phase (...)
Hello everyOne !!! i've a 90degree hybrid coupler implemented as a phase shifter with asnoft designer (circuit simulator) and i need to plot the phase of S21 (at the fixed frequency of 2Ghz) by varing the reactance on the other port (there are 4 port: 1 incident wave, on 2 and 3 there are two reactances (...)
Hello Everyone !! I need to simulate with ansoft designer v.2 an electronically controlled phase shifter using the circuit simulator (not planar EM) with microstrip tx-line component and lumped elements (diodes). can i do it ? Are there any complete project or paper about that ? Thank you guys !!!
A PI error amplifier would be my first guess. You didn't tell about the phase shifter range. Generally, an additional comparator for positive or negative phase difference and phase reversal switch are required to push the phase difference to the right part of the detector curve.
Are there any major tradeoffs between using a vector modulator or a VGA+phase shifter in a phased array? I'm thinking frequency of operation, ie, I haven't seen many VGA architectures for >5 GHz. Otherwise, there is no major difference other than the circuits themselves, you either change phase and amplitude (...)
Is it possible to use ustrip transmission line as phase shifter at 2.4GHz? Yes. and phase error below 5%. It depends on the bandwidth that you need. For a single frequency, you can design length to give exactly (*) the desired phase shift. I need 8 d
Hi amntt, are you thinking of tuning the phase of S21 to your desired results? If it it, try a phase delay transmission line? If you're thinking of designing the ACTUAL transistor and modelling its phase delay then sorry i can't help. Natnoraa
hello Friends, I want to design mmic 2 bit phase shifter circuit using advanced design system. for that i am in confusion how to choose mesfet model and how to by this product.
Hi every body I'm supposed to simulate a rotary field ferrite phase shifter in HFSS. in the phase shifter, the transverse magnetic bias field is rotating in continually around the ferrite material. the rotation of the bias field causes changing the polarization of the output wave compared to the input one (...)
There's no general solution without considerable restrictions of voltage and frequency range. You can't directly create a phase shift for a time domain waveform, you have to measure the pulse period and calculate a time shift. A digital delay of the sampled waveform might be the most simple way. Practically, use a dual-channel function (...)
I don't see you getting a regular CMOS ring to run that fast, but I could see using a CML 8-stage ring with one phase-flip (presumably you would be phase locking and the bias network offers this handle, too) and take the 16 phases off the 8 stages' true and complement (...)
A single-pole L or C circuit provides up to 90 phase shift per pole, and to get 180 phase shift, needs at least two poles (LC). In phase shifter or lumped balun designs very common is to use three poles to provide a 180 phase shift (CLC or LCL).
If you use a resistor, then any currents rectified in the varactor will not be stiffly controlled by your analog driver, and you may end up the phase shift that varyies by input rf power
Correct way to join L and R channels into mono signal is to pass them first through phase shifter circuits which maintain 90 between L and R in all audio spectrum and then join them. This is necessary because average phase angle of audio L and R is not 0 but about 45 (...)
Hi I'm new to designing phase shifter. I am thinking of making a reflection phase shifter using varactor diode. Ideally I want a 360 phase shift. I want to know what kind of varactor diode are out there. I am looking for something that are suitable for 1.2ghz frequency, can perform wide (...)
I'm designing a four bit wide band phase shifter (22.5,45,90,180 deg) which include series switches at input/output of each section combined with all-pass networks. My question here is that I'm not sure if I need to add DC blocking caps at the input/output of each section or do I just leave the D/S of the switch floating? Most of the (...)
Can anyone tell me how to simulate polyphase filter on ADS? What library I must use and how to show the phase simulation. It will be very helpful if you attach a complete circuit of polyphase filter along with the library that used. Thank you
I have done similar module before, input 2024 bits data and get 24 bits crc check sum. I designed a state machine with s0, s1, s2 phase, s0 is the initial phase and reset everything; s1 do the check sum calculation and ouput the original data; s2 do the check sum output. when in s1, the register is (...)
