Buy 2 samples until arrived after connected output antenna and supply it at 12Vdc draw more then 0,3Amp and start burned !!!!! on IC2. Second sample tested again at 12 Vdc , Not burned but hot too and power RF amplierf doesn't more than 10dB. For me very poor device maybe weren't 2 lucky pieces....

Goods received in perfect condition through postal services in about 4-5 weeks time, which is absolutely normal. The goods were checked in the RF workshop, and turned out to be capable of 1 Watt Maximum output by feeding 0dBm (1 milliwatt input), confirming the reliable almost uniform gain within the specified band (1-700MHz) of 30dB with linearity. We could not test it at higher power levels due to limitation of our Rf signal generator, whose output power level is limited to 0dBm (1 mW) max. Further investigation revealed that the module uses the following components with suggested power levels recommended by the manufacturer for reliable operation. RD01MUS1 (SMD CODE - K2) as the final stage rated for 520MHz, 1Watt SBA-5089Z-Sirenza. (SMD CODE - BA5Z) as the first driver stage. It may be possible to use this module at higher power levels, However we ourselves use the devices safely to half of their capacity for long term reliability for continuous operation. I am very happy to use them between 0.5 ~ 1.0 watts for our applications.... Very satisfied with the results, this will find use in various applications.

接続する前に、トランジスタの下にシリコングリースを使用してください。 最大電圧は12Vです。 トランジスタはクラスAで動作します。 12Vの場合、電流は0.45Aです。 1.25Wの出力電力、f=400MHzにおける27dBの電力利得。クラスB対称出力段ドライバとして適しています。 配達時間は60日でした。

Before connecting, use silicone grease under the transistors. The maximum voltage is 12 V. The transistors operate in class A. At 12 V, the current is 0.45 A. 1.25 W output power, 27 dB power gain at f = 400 MHz.It will be good as a class B symmetric output stage driver. Delivery time was 60 days.

良い値...しかし、出力段のバイアス電流を減らすことによって、より良く動作するように修正することができます。 抵抗R6を減らす必要があります。 小さな(10k)トリポットを使用して調整できます。

Good value... but can be modified to work better by reducing the bias current on the output stage. Resistor R6 needs to be reduced. Can use a small (10k) trimpot to make adjustable.

電源電圧が10ボルト100mA以下でも良好です。 金属製のハウジングに内蔵され、冷却フィンが交差する開口部があります。

Werkt goed bij een voedingsspanning niet hoger dan 10 volt 100ma. Ingebouwd in een metalen behuizing, met een opening waar de koelvinnen doorheen steken.

15.03 VDCで指定された値で電源を投入し、送信しました。 10秒で揚げる 12.0 VDC NO MOREのみを使用することを推奨します。 新しい命令を待っている。

Powered up on 15.03 VDC as specified and transmitted. It fried in 10 seconds. I suggest using only 12.0 VDC NO MORE. Awaiting new order.

Haven't yet tried it...but all other things I ordered all worked fine. So no fear that this one won't work. And great quality for such a price. I use it for all kind of experiments.
