Re: Footprint design...
The problem is the down part (see above picture) I have large part to attach heatsink, i don't know how to represent it in PCB layout? and how to make it in PCB [drill will not make such area in PCB]?
Re: Footprint design...
Hi
I'm unsure of how to develop the land pattern...
let me give some details, for PortalDXP...I have all footprint need in circuit, but the problem is how to add transistor with irregular shape !!!
I think to add empty place, and after PCB manufacturing, I will add...
hi dd2001,
No need to remove, Office 2003 based in Internet Community resource. In other words, When writing your report and need some template to fill, you can search with Word 2003 and get it from Online template in Microsoft website. When you need to add some Clips you can easily get from...
Re: Power Amplifier ...help
Thanks all for advice... :)
Dear BigBoss,
I'm still in my first step in RF design, last information I have about matching are matching!!! Power matching as I get from search considered for Tube PA. Please correct my information’s.
About the simulator, I'm already...
Re: Power Amplifier ...help
hi
I'm using MRF171A, problem appear in matching circuit...when I get tuned operation around the operating frequency gain increase significant and I have stability problem. in Cripps book, he say that adding small Resistance will give unconditional stable operation...
Re: Power Amplifier ...help
hi flatulent
I'm really not consider feedback/forward technique, since it complicated and need alot of optimization as I think. My aim is to build PA work properly with no damage :wink: , as transistor blowup be easily these day :) and take the experience of RF...
mrf171 amplifier
Hi
I need to design PA Class C @ 60MHz, with output power 10Watt.
using GMSK signal (linearity not issue), I failed to get stable with high efficiency in same time :cry: , my procedure:
1)- input matching network.
2)- RF transistor (MRF171)
3)- output matching network
4)-...
Hi
good work odyseus...its appear nice, but as usuall no one complete...!!
I think you forget to add title for webpages, you need to add in HTML header code, or use any S/W to add it.
Good work..... :wink:
