## How to desing 2 way divider ?

Doesn't work this way. With an ideal transmission line model (infinite common mode impedance), the circuit would work as a phase splitter. But infinite or reasonable high common mode impedance isn't feasible unless you place a ferrite core (transmission line transformer). L=100um suggests you want to implement the transmission line on-chip. But

## Noise Figure budget analysis for power combiner & divider

for every passive device the NF equals its own attenuation, so splitters have 3dB, and at combiners are not guaranteed the input signals are the same, thus they should have 0dB in that case I guess.

## How to design unequal Wilkinson divider according Taylor amplitude distribution coef.

Check this: and for more information google for "Qaroot and Dib wilkinson" I think you may go backwards from patches, for example 4 element array with distribution (in %) 20 30 30

## 12-way resistive splitter layout

I never layouted such a (lossy) resistive divider, only cascaded 3dB Wilkinson for 1:8 divider. Here, I would start from a 1:3 divider and then cascade 1:2 dividers. This way, you can easily create equal path length. Do you need the "round" layout, or can you h

## RF distribution Newbie question !

Disclaimer ; If you tend to be annoyed by lack of knowledge, please scroll on! I am a sound engineer, I have very limited knowledge in RF and analog circuits. I try to read and watch tutorials, but I get lost very quickly as I don't speak the basics of this language. The project ; I am building a small 2 way distribution box for my 2 wireless m

## Splitter for Triband Antenna

Hello All, I am using a Triband Antenna, and to get the individual Frequencies separately, please suggest some dividers or connectors kind of things. Thanks & Regards, Pravin

## Phase and level monitor of two signals

Hi, I want to monitor the phase and level of two signals. Actually there is one VFO which is split in two signals using a splitter, so the frequency is the same. Then one of the two signals is phase shifted using a PI LC network. To be able to set accurate 90 degrees phase and same level to the signals, I am thinking of doing this: Connect a comb

## 2 Power amplifiers in parallel

As was stated, if you split the signal and combine again, at the output of the PA you gain nothing IF the input power is the same. But IF you increase the input power with 3dB, you will get 3dB more output power (double the power in Watts). This is the reason that all the parallel or push-pull PAs need (at least) 3dB more input power than single on

## Conducted EMC measurement in offline SMPS

Page 31 of AN5 by states that a good way to reduce conducted emissions in an offline SMPS that is in a plastic enclosure is to put a metal plate under the enclosure... this metal plate being the same size as the power supply PCB. It says that this plate should be connected to the incoming Earth ground. I would have thought that thi

## Demodulation of an laser interferometer signal

You can put into RF double balanced mixer two signals: Fb which drives AOM/Bragg cell (LO port) and signal from photodiode (RF port) - as a result you will get at IF port signal proportional to displacement of your object (after filtering it). Your photodiode will give you a beatnote signal between two laser beams: unshifted laser beam taken by the

## Opamp buffered audio signal splitter- distributor 1 input to 3 outputs

Hello. i want to connect an audio signal to two or three different amplifiers.I have to make an audio splitter based on NE5532 or OPA2134.I came up with the following design.Any suggestions or improvements?Thank you!!!

## Thermal noise addition after a combiner.

I am using SystemVue (from keysight) software to simulate. I have a source which gives me a signal and source thermal noise which is -173dBm/Hz at room temperature. Now when I pass this through a hybrid 90. i am getting the same noise floor at two outputs, i.e., -173dBm/Hz and the signal is degrated by 3 dB at each outpu

## Problem: S11 of LCR circuit through directional coupler

For non-euclidean complex transform reasons on the smith chart, i do not think you can tolerate the 20 dB loss of a directional coupler and see what you want to see. You will not have the accuracy. Try a 3 dB power spliltter. 144913 If I understand right, the splitter will send power to

## This is not working for me (designing balanced amplifier, power splitter)

not that familiar with that one piece of software, but you are using a branchline 90 degree hybrid power splitter? Well they are very narrow band, so they will never work over .3 to 1.5 GHz range. The phase shift will not remain 90 degrees, and the split will not remain balanced. Analyze just the power splitter without the transistor in there an

## Hum with single-to-split power supply for the equalizer.

The zener diode/emitter follower has no error amplifier so its voltage regulation is pretty bad and produces ripple. The two transistors voltage splitter is feeding half of that ripple directly to the (+) input of the opamp with no filtering. The 2 transistors splitter can produce maybe 100mA but its load is the (+) input of the opamp that might us

## ADS genesys 10 way microstrip splitter

Hello, is it possible to design microstrip1o way power splitter? i know that a T splitter splits into two , but `10 way requieres two components of 5 way splitters. Thanks

## Split GPS antenna to 2 receivers?

If you place the LNA after the antenna and before the 3dB splitter (for the LNA let's assume 0.5dB NF and 15dB gain), the total increase of the combined noise figure will be 0.62dB (only 0.12dB increase for LNA + splitter). Myself I am using a single GPS antenna followed by an LNA and a 4 way splitter, going to 4 receivers.

## Why so much noise on 16 MHz

Sounds like you have already proven that the noise is coming in on the antenna. Now the question is, whether this is ambient noise or self-induced. How about box- shielding the receiver as another "diagnostic cut" to prove / disprove local coupling? I don't see anything like a spectrum analyzer plot from the antenna, to say just how filthy the air
