RF Power Transistor Packs 1.5 WChiseled for UHF pulsed radar applications, the Model 0405SC-1500M RF power transistor exploits state-of-the-art SiC technology to provide 1,500W of peak power in a compact single-ended package that replaces push-pull balun circuitry found in conventional silicon BJT or LDMOS designs. The device is a common gate, class AB transistor designed for UHF frequencies from 406 MHz to 450 MHz. It is built with 100% gold metallization and gold wires in a hermetically sealed package suitable for use in weather radar and over the horizon radar applications. Other features include a medium pulse format of 300 µs at 6%, a typical power gain of 8 dB, and a drain efficiency of 45% at 450 MHz. MICROSEMI CORP., Irvine, CA. (800) 713-4113.
MixW3 is a next step on the way to the upcoming multiplatform MixW project There is a lot of work to do, but now we'd like to present a prototype of future MixW4, a very simple DigiPan32 project (see below). MixW3 proposes new Telnet dialog with talk over DxCluster support and a possibility to have a backup copies of your log on our server, dx.mixw.net. Logs can be password protected. MixW3 upgrade is free for those who stay with us 10 years or more. MixW3 is free for beta team, HAM radio developers and DxPeditions. Download MixW 3.01a Check registration |
