Googling 1N23 produces 8000+ hits... including a "Simple 2.4 GHz SWR Meter": (http://www.qsl.net/n9zia/24swr/index.html). I see RF Parts (http://www.rfparts.com/) sells the 1N21 and 1N23. MicroMetrics (http://www.micrometrics.com/) makes them, as well as various schottky diodes suitable for sampling. 73, Bryan WA7PRC Interesting but this is not what was requested. Also, try "Hot Carrier Diodes" HP had some that wetn't too bad -- Jim |
