https://community.nxp.com/t5/Wireless-MCU/MMG30271B-amplifier/m-p/1724221#M15667 <P>I bought several MMG30271B chips and made a PCB for amplifying a signal of 3 GHz. I used solutions&nbsp; for 2496–2690 MHz and&nbsp;3400–3600 MHz described in the datasheet and tried to tune input and output circuits. Unfortunately, I can't get gain more than 2.4 dB of 3 GHz (maximum gain is 11.8 dB at 2.2 GHz). I also moved the chip to the factory made PCB for another amplifier and got the same results. What should I do to increase the gain at 3 GHz?</P> Sat, 16 Sep 2023 22:42:02 GMT Albom 2023-09-16T22:42:02Z https://community.nxp.com/t5/Wireless-MCU/MMG30271B-amplifier/m-p/1724221#M15667 <P>I bought several MMG30271B chips and made a PCB for amplifying a signal of 3 GHz.
