How could it be 28~30dBi gain "Model: GJX-698-2700-30"? Can anyone explain please!
I search for 915MHz high gain antenna and found this:
https://www.amazon.com/Tgoon-GJX-698-2700-30-Omnidirectional-Antennas-Connector/dp/B0B2VL5NL3
Does it means with the max input power +/- 2dBi antenna gain ...
Thanks for your comment.
But the substrate structure cannot be changed due to relating to other parts of other works, they just request me to re-design a microstrip power splitter for a 10W RF signal (each branch) to two antenna ports
the trace at each end port must use the width of 1.1mm (for...
I need to design a microstrip power splitter for high power RF signal of about 40dBm (10W)
on a PCB of FR-4 (Er=4.5) with 4-layers( 0.5oz/0.11T/1oz/0.2T/1oz.0.11T/0.5oz)
So, by using ADS-LineCal tool, the calculated 50-ohm trace impedance results in a very small width of the trace 0.192mm
I...
Thanks, so what does it means of 0.38" = ?
Anyway,
L1 — 3 Turns #16 0.25″ ID = ?uH
L2 — 6 Turns #16 0.5″ ID = ?uH
L3 — 7 Turns #20 0.38″ ID = ? uH or part number please
Need help with coil inductor marking and reading !?
what does it mean?
I got this from datasheet MRF426, so I can't convert its parameters into real inductor values = ? uH
L3 — 7 Turns #20 0.38″ ID
7 turns = number of turns
#20 = ?
0.38" = ? copper wired diameter ?
ID = ?
You are right, it is a square wave at the OSC2/CLKOUT (the pulse width of duaration T=360us for 'one symbol') but it is not a simple squarewave of a series '1' & '0' : 0101010101010101...
It is hardcoded to include data, such as if GP0/GP1/GP2/GP3 (equivalent to 4 buttons) at standby mode...
Based on the OOK/ASK modulation
To reduce the Adj channel leakeages (offset 12.5KHz/BW=8.5KHz) ,
it should be ... slower symbols or smoother symbols
Or
Then, how do I can control OSC2/CLKOUT data rate at lower/higher frequency ? without using extra component such as LTC6993 IC
Recent...
Thank you so much
That's what I need, It doesn't matter. I can reprogram IC to get data output at 8KHz
The IC is
PIC12F683-I/P - PIC12F683 Flash 8-Pin 2kb 8MHz Microcontroller
Dear Expert,
Is there anyone who knows or has knowledge about this IC ?, I want to know its part number or a similar IC function (it doesn't have silk screen name on top of the IC so I don't know its name, but I know its functions)
Its function is a one-shot random pulse generation IC which is...
Dear all experts and edaboarders,
I need help or suggestion, related to 5GHz Antenna design for UAS & GCS (Unnamed Aircraft System & Ground Control System)
I am looking for any references document related to the above topic, if you have it please share it for me
It can be documented (such as...
You're so sweet, Thank you @volker. I got it.

I want to convert the output plot from dBm to mV
But I don't know how to express exponential equation in ADS as Eqn
I'd checked it out from ADS help, but only find the exp() ...
P[dBm] = 10*lg (Po[mW]/1mW]), & consider Lload=50-Ohm
For example: how can we express a^b in ADS Equation ...
I also don't know why ? and what are the reasons?, but a lot of our products on sale already get A/S because of damaged LNA.
And I also have a wonder that the BL022 itself has some problem; that's why Berex company discontinued this IC and release a new name BL022A with same spec's.
I have designed a diversity antenna distribution system for UHF broadband
My first design as Case 1 (attached picture)
Port 1 is comming from Antenna 1
Port 2 is comming from Antenna 2
It is a diversity antenna distributor system to multiple receivers.
If port 1 is fed by 10dBm RF signal the...
