## Antenna average gain vs peak gain

The peak gain is the point in 3D space where the antenna gain has maximum value, while the average gain is averaging all the points in that 3D space.

## AC voltage sensing using AMC1100

difference between input and output is 7 volt maximum. but I need to sense the voltage in the range of 1 Volt. Don't understand this statement. How do you observe it? AMC1100 is specified with maximum gain error of +/- 0.5% at 25 °C. Means the measurement must be adjusted if you need higher accuracy. I suggest a different circ

## How to design a difference amplifier with unity gain.

In your block diagram, use have used the classical symbol for an opamp (voltage-in and voltage-out). Hence, in my previous answer I have assumed that you are using such an amplifier (off-the shelf). However, in case you are designing another amplifier by yourself (which - as it seems - has no low-resistive voltage output) you cannot use the gain ex

## How to choose Driver and Power amp in RF Transmitter part.

Hi, Currently I am analyzing Tx part and given one Driver amp. and one two stage or three stage Power amp. Can some one help to understand what is the difference to using of two stage or three stage PA except gain if it is possible to get power with 2 stage. And for example given OP1dB =33 dBm and what will be Pavg in this case?

## changing the input of an inverting op-amp

The opamp has an extremely high gain but the negative feedback reduces the circuit gain to a useable amount. Therefore the difference voltage between the inputs is extremely low. Use Ohm's Law to calculate the output voltage since an opamp has an extremely low input current: 1) Input resistor to inverting opamp= 10k, feedback resistor= (...)

## Inverted F versus Patch Antenna

The main difference is the antenna pattern. Patch antenna pattern looks like this: and inverted-F antenna pattern looks like this:

Hi, I am designing a mixer for a bluetooth radio transmitter for a school project. I am having trouble figuring out how to run simulations for the following specs that I have to meet. gain = 0dB Do I just connect one port at input and one port at output and use sp analysis to measure s21? OIP3 => -5dBm I have this simulation for the power a

## What is difference between radiation gain and antenna gain?

Hi What is difference between radiation gain and antenna gain? Thanks alot

## 30mV systematic offset - folded cascode

... You have also unbalanced output stage and first stage which can produce additional offset. I think this shouldn't matter at gain=1 feedback (and no gate input current, of course).

## How to analyse the uncertainty of nominal coefficients in a circuit design?

Hi, My circuit has a gain phase detector that generates two output voltages, VMAG and VPHS which is related to the magnitude ratio and phase difference of the input signals (VA1 and VA2 ) by the transfer function: 126313 The magnitude ratio, |Z| and phase difference, _

## Difference between Momentum Microwave and FEM Simulator

Hi, For a planar structure, the MoM (ADS momentum) method is a good one. You gain in time because the matrix to solve is reduce. With FEM, you solve the problem in three dimensions the matrix is more complex. For 3D structure FEM is preferable. I already designed some filters with ADS momentum and the simulation was quite good and fast. Good work

## Why do we use "AC1" while doing ac analysis in LTspice ? what does AC1 mean?

when i entered AC 2 or AC 3 the shown gain and ugb is doubled and tripled , how ? You are confusing output voltage with gain. gain is Vout/Vin, so if Vin is unequal 1V, you need to calculate a ratio.

## stb simulation - local loop of gain-boosting amp

Hi, below schematic is a fully-differential gain-boosting opamp that I'm working on right now. I want to check the stability of a local loop that is comprised of gain-boosting amp and a source follower. So, I inserted 'diffstbprobe (red color)' as below, set it as a probe instance, and ran stb simulation (for now, I'm using ideal CMFB, so didn't

## The difference between gain phi and gain theta in hfss

Hello, I have two antenna and i would like to visualize the gain of this antenna, so i m find that in HFSS, it have two curves: the gain phi and gain theta in hfss, Can someone explain me the difference betwenn the two angles Thanks in advance

## Two Sweeps for the Same Antenna

please explain more on what software you using to simulate and what difference in results you seen. is it S-parameter difference or gain and efficiency difference?

## OPAMP to ensure both terminal are equal?

For a good understanding of the feedback principle it is necessary, I think, to realize that the voltages at both inputs are NOT equal (due to negative feedback). This is because the opamp always needs an input voltage difference to produce an output voltage. However, due to the large open-loop gain Aol of the opamp this differential input vol

## conversion gain of a N-path mixer

Hi all, Can anyone suggest what will be the conversion gain of a N-path mixer (say, 4-path) as compared to the conversion gain of a single-path current driven mixer? What will be difference in the two conversion gains? Thanks in advance. Indrajit

## MIC923 opamp as voltage follower

Yes, that means the op amp will be unstable if used as a +1 follower. A minimum closed-loop gain of +2 for a non-inverting amp or a gain of -1 for an inverting amp is the same from a loop-gain point of view since in each case you have two equal value resistors going to the op amp (-) input. The only difference between the (...)

## What is the Difference between IIP3 and IPIP3?

Hi everybody. I would appreciate if anyone could help me with the differences between IPIP3 and IIP3. I think IIP3=IPIP3/gain. Am I right? In AGCs usually IPIP3 is reported instead of IP3? why and what is it? Thanks.

## R&S CMU200 RF output attenuation

Hello, it is written in the CMU200 documentation that we can add some attenuation on the RF output. "The softkey Ext. Att. Output defines an external attenuation (or gain, if the value is negative) at the selected RF output." However I get gain if the value is positive, I've checked it with a spectrum analyzer. Is it normal ? Regard
