The operational frequency is around 1GHz , Thanks for the suggestion about switch usage , But here I don't want to use the switch that's why I came across these options .
Where The difference between the T-junction and Y- junction are in the layout pcb lines only.
If I considered the...
Hi ,
I'm planning to place two antenna's UFL and SMA supported on my RF board . among them one is optional for a particular time. So , I've two different approaches or placement methods , one is T-Network method and the other is Y-Junction method .
Can anyone please mention which one is the...
Hi,
I am going to use the below Filter in my RF application. One thing I could not understand is: finding out the DC blocking capacitors' values which are recommended as a part of supporting circuit. Please, let me know if I should use the DC blocking caps, if yes, what can be the recommended...
Sorry , I have tested that attenuator by depopulating from the board , The foot print it self designed like that . the attenuator shows short between all the pads.
Hi ,
I'm including one SMD attenuator in my RF board . When I'm populated that attenuator on the board it shows like RF signal gets shorted with ground. I tried multiple times and come to conclusion like RF signal to ground connection establishment is just because of attenuator. I was tested...
Hi ,
I wanted to implement one optional antenna on to my R&D Transceiver board. There will be one fixed SMD antenna on my board , just being in safe side I optionally wanted to connect an SMA/UFL antenna connector to it. Can anyone suggest me that how can I achieve that one. I come up with...
Hi ,
While i'm exploring to select an antenna for my RF applcation , I came across multiple datsheets .
I have selected 50 Ohm impedance antenna for my case.On other end of amplifier also I've 50 Ohm of impedance . So I feel like no need of external mathcing circuit to be placed to match...
not exactly @ 175 degree celsius . but above the junction temperature around 150 C.. but In my case The load will take 2A of current once for every minute , I mean not a continuos supply . So does it make problem in this case also ?
I am searching for a voltage regulator which gives output voltage of 3.3V, 2A with input of 7.5V min. I have seen Voltage regulator which has the junciton temperature range like 0 to 125 degree celsius.
there is calculation for junction temperature related...
Hi ,
I have a doubt related to Resistor power rating , How much it is important to consider the power rating for an Resistor ?
Generally people saying that the power rating for a Resistor should be greater than the power dissipates
through it . Is it a serious thing to consider practically...
