Dear Petr, I have just built an LF amplifier using a TBA810S to drive my antenna metering bridge. Output has been 3,5 watts at 136 kHz and 15 volts supply voltage. 500 kHz was not on the table at tha
Hi Petr - I use the TDA2030 as a pre-amplifier to produce a few watts in my 136 kHz linear PA. The spec implies that it should still have some useful gain at 500 kHz - I'll be most interested to hear
Hi all, My intention is to build a small transmitter up to some 10W for 136 and 505 kHz, this time not the D class, but B or AB class. I think of employing AF amplifiers such as TDA2003, TDA2030, or
