Re: DEtECtOR DioDe
hello sekharareddy!
Thank you for advice. I visited this macom.com and found different type of detector diode. For example. i found MA4E2501 series V5 which would work up to 26 Ghz. But i don't know how to mount this diode to my substrate. And i have qustion: Does surfmount...
hello All!
I design the matching network for push-pull amplifier and can't understand what is gate-to-gate connection.
Could anybody explain me with it?
ZSOURCE = Impedance of the external input matching circuit as seen
from gate to gate.
I can't understand 'gate-to-gate' . Each of two...
Rfsurfer, thank you very much.
I have almost understood. at first, sorry for my enlish, i speak little. it presents some difficulties for me and other people. That's why i have some questions? Could you advice me?
I read the paper which attached here. And i don't understand why the...
thank you

Thank you.
I have such amplifier. I calculated overal OIP3 about 35dbm, but AWR give me 33.57dBm. I dont't understand why result is different? Can i trust AWR or derivation of total OPI3? or maybe i'm mistaking
Added after 7 minutes:
Sorry, amplifier...
Hello All.
Can anyone help?
I calculated the total 0IP3 of two amplifier block.
1st block has G1(power gain)=10dB and OIP3-1(output intercept point)=30dBm.
2nd block has G2(power gain)=6db and OIP2-2=35dBm
using derivation 1/OIP3=(1/OIP3-1*G2) + (1/OIP3-2) I calculated over 0IP3...
Hi
at first let me thank all of you.
...just I've heard about improving IP3 by optimization of the input and output matching circuits. Anyone know about it?
Safwatonline. Hello.
Sorry, but I don’t understand fully what you mean. It's possible because of my English. Veff is voltage of DC supply? Do you suggest to spill the input power for couple MOST and amplify its separately, and after couple power at out (likely, balanced amplifier)?
If I’m...
VSWR.
I use such FET transistor - MGF2425A. Data sheet in attachment file. I'm designing for MAX gain usins S-parameters by standart techiques.
Amplifier operate at class A. I would like to enchance IIP3 at fix output power. Is it possible?
Hello! Who can help?please
I need this information.
How to reduce intermodulation distortion of linear PA (12Ghz operating frequency, power of out = 1000mW at 1dB compressino point) ?? What techniques can be done to improve IP3?
If possible point out the refference to internet source...
Hello everyone!
I have some question.... Could you help me?
how to improve IP3? Can we use different type of amplifier, for a example, push-pull or balanced to decrease intermodulation distortion?
