    RF Amplifier @ 200MHz

    bfg198 thank you for your reply...!!... a little misunderstanding i have to correct... the gain is needed along a 7MHz band on a center frequency of about 203MHz (meaning from ~ 199.5MHz to 206.5MHz) and not from 7MHz to 200MHz...sorry if you were mislead.

    RF Amplifier @ 200MHz

    bfr96 spice model hey all.... i'm zachi's partner working with him on the same project. We used the RF Generator to give us a -30dBm @ 200MHz as an input test signal.the Output was measured using a spectrum analyzer. after playing with the values of the resistors and capacitors, we got the...

    tda5660 datasheet i figured that the saw filters were for IF Frequency when i started looking for such a filter and realized that their central frequency is about 40MHz. as for designing my own filter, well i am currently trying that. i planned a 2*4 order Chebyshev Band pass filter to meet my...

    tda5660 pdf i can see that this integrated circuit is similar to the tda5660, but i didn't see any implementation of a vsb filter... i need a VSB Filter for a video signal modulated with the tda5660 . the video carrier is at 203 MHz and the sound carrier is located after 5.5 MHz . can you...
