Hi,everyone
Is there the type of chip with mxier and amplifier integrated together? the Rf of mixer is about 400Mhz and the IF is 21.4Mhz, the required gain of amplifier part had better
to be more than 80dB. If not,Pls introduce some single IF amplifier chip with the gain of more than 50dB.
(we have used amplifer modules connected to get about 100dB gain,but the self-excitation hardly to be eliminated.)
Great Thanks!
