This is a thread to gather up possible alternative parts & solutions for american RF & analog ICs due to the need to diversify the supply chain in face of politicization of electronic parts. I will update keep this post updated as new solutions are added. Note: avoid discussing politics. I have nothing against Americans but like any other business we have to be risk-averse, and recent events have shown that single sourced parts are a substantiated (and not just theoretical) risk. The criteria for a part to be included on this list are simply that it needs to be manufactured by a corporation with majority (50%) of operations not in the US, since that was the main criteria that was used last time with the embargo against Huawei, OR if there are reasons to believe that a specific corporation can not be used as part of a trade embargo. Analog ICs * High speed ADC * 3PA1030 (50MSPS 10bit) * 3PEAK - https://list.szlcsc.com/brand/926.html * High speed DAC * GM7123C (330MSPS 10bit) - drop in substitute for ADV7123 * High speed op-amp * SGM8061 * MS8051 * TPH2501 * GS8051, GS8091 * RS8751 * SG micro - https://list.szlcsc.com/brand/280.html * Gainsil - https://list.szlcsc.com/brand/11403.html * Low noise LDO * SGM2028 * Power management/misc * TP199 (current sense amplifier) - INA199 substitute * FP6373A (buck IC) - 5V 3A SOT23 * JW5033S (buck IC) - 18V 2A SOT23 RFICs * RF switch * MXD8625C - spdt, 35dBm * MXD8641, MXD8661 - sp4t, sp6t * CanaanTek - https://list.szlcsc.com/brand/11832.html * Maxscend - https://list.szlcsc.com/brand/11684.html * Lansus (huawei) - https://list.szlcsc.com/brand/11734.html * MMIC amplifier * TBD * RF mixer * TBD * RF synthesizer * TBDOther * Microcontrollers * GD32 (risc-v), ESP32, Kendryte K210, ... * FPGA * Gowin, Anlogic, ... |

Ah, the counterfeits thread ;) |

At the end of this war, the Chinese will have a full line of cheap mass production components and USA will have a very expensive line on low quantity state of art chips who only US government and military will be able to buy, Everbody else will buy the Chinese ones even with a 100% tariff |

Added DACs and power management chips. I am still looking for RF synthesizers and mixers. It is the last piece of the puzzle that will allow a fully second-sourced NanoVNA V2 and other RF test equipment. I can actually use diode ring mixers and get similar performance, but a simple Gilbert cell IC can't be very hard. |
