| Need to find SPDT SWITCH |

| dhumx:
Hi all, I'm trying to build a project has 2 local osc that generate frequencies on VHF. The 2 local osc must be connected to a SPDT switch, the spdt switch that I would like to have is the one that can be drived by the clock of arduino. Is there any SPDT switch that do the job? I have no idea what switch to use since all the SPDT switch I have worked before are all mechanical. |

Have you looked at the CD4053 or its lower voltage variant, the 74HC4053 ? That is three, SPDT electronic switches on a chip each driven by a logic level signal. The -3dB frequency is 150-160 MHz so although that is VHF does not cover the entire frequency range of VHF. |

Skyworks, among others, make them..kHz to gHz. Search Digi-key or eBay for Skyworks spdt |
| Benta:
The 4053 will have major crosstalk/feedthrough problems. Check Vishay/Siliconix for good analog switches. |
