They focus on output power and spectral features. For wireless applications, it&rsquo;s important to achieve high output power at the 1dB compression point. This is especially true for standard multilevel modulation schemes. The team worked with a Japanese university to create a bonding method. This method directly integrates InP-based UTC-PDs onto SiC substrates. It uses SiC&rsquo;s excellent thermal conductivity. This innovation has resulted in photomixer devices that now exceed 1 mW in output power at the 1 dB compression point. That&rsquo;s about ten times better than older devices.<\/p><h4>\u3053\u3061\u3089\u3082\u304a\u8aad\u307f\u304f\u3060\u3055\u3044\uff1a <a class=\"p-url\" href=\"https:\/\/itbusinesstoday.com\/ja\/iot\/cloudera-joins-ai-ran-alliance-to-boost-ai-data-innovation\/\" rel=\"bookmark\">Cloudera\u3001AI\u30c7\u30fc\u30bf\u30a4\u30ce\u30d9\u30fc\u30b7\u30e7\u30f3\u3092\u4fc3\u9032\u3059\u308bAI-RAN\u30a2\u30e9\u30a4\u30a2\u30f3\u30b9\u306b\u53c2\u52a0<\/a><\/h4><p>\u5f93\u6765\u306e\u30a6\u30a7\u30fc\u30cf\u30dc\u30f3\u30c7\u30a3\u30f3\u30b0\u306f\u3001\u5927\u91cf\u751f\u7523\u306b\u306f\u53b3\u3057\u3044\u3082\u306e\u3067\u3057\u305f\u3002\u63a5\u5408\u9762\u7a4d\u304c\u5927\u304d\u3044\u305f\u3081\u3001\u5c0f\u3055\u306a\u6b20\u9665\u3067\u3082\u5927\u304d\u306a\u554f\u984c\u306b\u3064\u306a\u304c\u308a\u304b\u306d\u307e\u305b\u3093\u3002\u307e\u305f\u3001\u6750\u6599\u52b9\u7387\u3082\u91cd\u8981\u3067\u3059\u3002\u5f93\u6765\u306e\u65b9\u6cd5\u3067\u306f\u3001\u9ad8\u4fa1\u306aInP\u6750\u6599\u306e\u307b\u3093\u306e\u4e00\u90e8\u306b\u4f9d\u5b58\u3057\u3066\u3044\u307e\u3059\u3002<br>\n\u3053\u308c\u3089\u306e\u554f\u984c\u306b\u53d6\u308a\u7d44\u3080\u305f\u3081\u3001OKI\u306fCFB\u6280\u8853\u3092\u63a1\u7528\u3057\u307e\u3057\u305f\u3002\u30d7\u30ea\u30f3\u30bf\u30fc\u696d\u754c\u306720\u5e74\u4ee5\u4e0a\u78e8\u304d\u4e0a\u3052\u3066\u304d\u305f\u3053\u306e\u6280\u8853\u306f\u3001InP\u7cfb\u7d50\u6676\u819c\u3092\u30c7\u30d0\u30a4\u30b9\u30ec\u30d9\u30eb\u3067\u5206\u5272\u3002\u5fc5\u8981\u306a\u90e8\u5206\u306e\u307f\u3092SiC\u30a6\u30a7\u30cf\u306b\u63a5\u5408\u3002\u3053\u308c\u306b\u3088\u308a\u3001\u30dc\u30f3\u30c7\u30a3\u30f3\u30b0\u306e\u6b69\u7559\u307e\u308a\u304c\u5411\u4e0a\u3057\u3001\u6750\u6599\u52b9\u7387\u304c\u6539\u5584\u3055\u308c\u307e\u3059\u3002\u3053\u306e\u30d7\u30ed\u30bb\u30b9\u306b\u3088\u308a\u3001\u30a6\u30a7\u30fc\u30cf\u30b9\u30b1\u30fc\u30eb\u3067\u306e\u63a5\u5408\u304c\u53ef\u80fd\u306b\u306a\u308a\u307e\u3059\u3002\u3053\u308c\u306b\u3088\u308a\u3001\u30dc\u30f3\u30c7\u30a3\u30f3\u30b0\u306e\u6b69\u7559\u307e\u308a\u304c\u7d0450%\u304b\u3089\u7d04100%\u306b\u5411\u4e0a\u3057\u307e\u3059\u3002\u307e\u305f\u3001\u6750\u6599\u306e\u5ec3\u68c4\u3092\u524a\u6e1b\u3057\u3001\u74b0\u5883\u3078\u306e\u5f71\u97ff\u3092\u8efd\u6e1b\u3057\u307e\u3059\u3002<\/p><p>NTT\u30a4\u30ce\u30d9\u30fc\u30c6\u30a3\u30d6\u30c7\u30d0\u30a4\u30b9\u306f\u3001SiC\u57fa\u677f\u4e0a\u306bUTC-PD\u30c1\u30c3\u30d7\u3092\u958b\u767a\u3057\u307e\u3057\u305f\u3002\u3053\u306e\u30d7\u30ed\u30bb\u30b9\u306b\u306f\u30dc\u30f3\u30c7\u30a3\u30f3\u30b0\u7d50\u6676\u819c\u3092\u4f7f\u7528\u3002\u30c6\u30b9\u30c8\u306b\u3088\u308b\u3068\u3001\u3053\u308c\u3089\u306e\u30c7\u30d0\u30a4\u30b9\u306f1dB\u5727\u7e2e\u70b9\u30671mW\u4ee5\u4e0a\u306e\u51fa\u529b\u96fb\u529b\u3092\u767a\u751f\u3057\u307e\u3057\u305f\u3002\u307e\u305f\u3001\u512a\u308c\u305f\u76f4\u7dda\u6027\u3082\u7dad\u6301\u3002\u6697\u96fb\u6d41\u306f\u3001\u5f93\u6765\u306e\u30dc\u30f3\u30c7\u30a3\u30f3\u30b0\u6cd5\u306e\u7d043\u5206\u306e1\u306b\u4f4e\u4e0b\u3057\u307e\u3057\u305f\u3002\u3053\u308c\u306f\u3001\u65b0\u3057\u3044\u6280\u8853\u304c\u30dc\u30f3\u30c7\u30a3\u30f3\u30b0\u4e2d\u3082InP\u30d9\u30fc\u30b9\u306e\u819c\u306e\u7279\u6027\u3092\u7dad\u6301\u3059\u308b\u3053\u3068\u3092\u793a\u3057\u3066\u3044\u307e\u3059\u3002<\/p><p>\u3053\u306e\u30c1\u30fc\u30e0\u30ef\u30fc\u30af\u306f\u3001\u9ad8\u51fa\u529b\u30c6\u30e9\u30d8\u30eb\u30c4\u6280\u8853\u3092\u3088\u308a\u5b9f\u7528\u7684\u306a\u3082\u306e\u306b\u3059\u308b\u305f\u3081\u306e\u5927\u304d\u306a\u4e00\u6b69\u3067\u3059\u3002<\/p><p>\u4eca\u5f8c\u306b\u5411\u3051\u3066 <a href=\"https:\/\/www.oki.com\/\" data-no-translation=\"\">OKI&nbsp;<\/a> \u305d\u3057\u3066 <a href=\"https:\/\/www.ntt-innovative-devices.com\/\" data-no-translation=\"\">&nbsp;NTT Innovative Devices Corporation<\/a> plan to begin mass production in FY2026.
