[Amps] Advanced Power Technologies ARF1505

[mike kendall]

With a gain of approximately 16dB, it could have about 67 watts going into a shunting resistor and still get 1KW out of a pair with a 100 watt transceiver.  I think this is similiar to the way they do it on the the Ameritron ALS-600 by looking at the size of the input resistor on that amp.  The 5400pF is a rating at 1mhz.  Further down the spec sheet they have input impedances for 2,13.5, 27, 40 mhz and they look to be substantially different with ratings that are shunted by a 25ohm input resistor.  I am calling the company tonight for more information as they do advertise it for broadband HF amplifiers on the news release from a few years ago.

On the output perhaps. 5000pF Cin will make broadband input matching 
very interesting!
