    Help me design a Power Amplifier Class C at 60MHz

    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...

    Help me design a Power Amplifier Class C at 60MHz

    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...

    Help me design a Power Amplifier Class C at 60MHz

    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...

    Odyseus's RF & Micowave Theory site now active!

    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:

    TSMC 0.18 RF designkit for ADS2005A

    Re: @DS2003 design kit * Dear dibl01 As I know Agilent will not support layout editor any more, since they join Cadence with agreement using there Layout tools "Costume IC" and "SoC"....hence most of ADS design kit will not contain DRC, thats why they are small size...as I think :idea: *...
