Hello,
Can a device that works well for a CW mode application, be assumed to deliver sufficiently well if not as well in a pulsed mode application?
If not, what are the factors to determine which device can be used safely in the pulsed mode.
The reason for the question is that a lot of...
Thanks for the replies.
I checked and :
1. The input modulated signal is in the range of 0 dB.
2. The detector is a PIN diode detector IC.
3. When the device is said to have failed, there is a increase in the current consumption.
In the meanwhile, am checking w.r.t. biff44's suggestions...
Hello,
Recently came across an interesting problem. In a circuit, a Triquint devicce was being used which has a capability of 39 dBm P1dB. The deivce was working fine until a modulated input was applied. The output power then dropped to 30 dBm and also the device failed (died :) ). Without a...
Thanks for the replies. I understand the point made here about using the combiners. The replies only clarify it further. My question though is:
Let's say we have a PA whose otuput is 1 KW, can I feed this 1 KW to the next PA to get a further amplification to let's say 2 KW? I assume this is not...
Hi,
Could someone please explain what is meant by:
1. Passivated Body of a connector - how does this parameter affect the performance.
2. "Center conductor is Captivated"
I came across these while going through some SMA connectors guides.
Thanks.
Hi Alex,
Thanks for the reply. I've attached the datasheet (MRF6VP121KH) to this message as an example. The typical performance parameters of this device refer to a 128 usec. Is there any parameter to see if we can use this device safely for a lesser or higher pulse width?
Hope this clarifies...
Hi,
Do the parameters pulse width and duty cycle on the datasheet of a device effectively mean the same data reperesented differently?
If yes, in that case am I right in assuming that a device for which the datasheet mentions a pulse of let's say 128 µsec can be used for pulse operation of 35...
Re: What r the responsibilities of field Application Enginee
Hi,
I just found this thread while looking for info on a Field Application Engineer job profile I have recently applied for. I have completed my post graduation in 2009 and since then worked for a company that initially hired me to...
Thanks for the replies.

Hi Miguel,
Thanks for the reply. If this is case, then practically, are active up converters never employed?? If they are then are there any specific applications for which they are preferred?
Hi,
In an application note for mixer parameters from Maxim, it is mentioned that:
"A major advantage of passive mixers is that they can also be used as frequency upconverters."
The link for the application note is: **broken link removed**
Does it mean that active mixers have some...
Hi,
A recent interview question. Can a transmission line be formed if the ground plane is removed from a microstrip. In other words, you have only a dielectric and a small width conductor trace on top. Can field propagate? If yes, which modes would propagate? Can Quasi-TEM propagate in such a...
Hi,
I have gone through a lot of material that says that inductive degeneration is the best for stability. I understand it being better than a resistive feedback because of the loss a resistor would introduce. But why is it better than a capacitive degeneration?
