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.

Prima del collegamento, utilizzare grasso al silicone sotto i transistor. La tensione massima è di 12 V. I transistor operano in classe A. A 12 V, la corrente è di 0,45 A. Potenza di uscita 1.25 W, guadagno di potenza 27 dB a f = 400 MHz. Sarà buono come un driver di stadio di uscita simmetrico in classe B. Il termine di consegna è stato di 60 giorni.

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.

Buon valore... ma può essere modificato per funzionare meglio riducendo la corrente di polarizzazione sullo stadio di uscita. Resistore R6 deve essere ridotto.

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.

Funziona bene con una tensione di alimentazione non superiore a 10 volt 100ma. Costruito in un alloggiamento metallico, con un'apertura attraverso la quale si incrociano le alette di raffreddamento.

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

Acceso a 15.03 VDC come specificato e trasmesso. Si è fritto in 10 secondi. Suggerisco di usare solo 12.0 VDC NO MORE. In attesa di nuovo ordine.

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.
