Instead of copying such complex info esp. RF curves graphics - please download & examine its Datasheet per weblink below.
Opens a folder of Datasheets --> select filename --> Datasheet -''AmpliTech'' APTHP480 - 430to530MHz 20_28W. Notes: if link doesn't work e. Or just look around in that folder if a similar filename exists. "Random characters" at the end of the weblink are auto-generated by our server, so I can't make them nicer or memorable (characters function as a password for private folders, but in your case is irrelevant because a Public folder [no password]). ====================================== A synopsys of selected few specs, is already listed above under the section "Item Specifics", but we urge you to download a "real" datasheet to understand these HPA Amplifiers/specs, properly.Nothing to assemble, no work or guessing if assembly would work - just connect & use. It is not a"half-baked" "do it yourself kit" which are cheap for a reason, this one is not quite cheap. As one example, I point out thermal paste (TIM material) involved, is not a commodity cheap (silicon or similar paste, used in computer CPU's), but instead is a proprietary Silver Nanospread, which is both E-conductive & Thermal conductive, discovred to result in better VSWR In/Out, versus desigs based on the same IC's yet mounted on more common TIM's. Another example, is we've tried to burn out one unit in a destructive test, before finalizing design, but was difficult to destroy - in fact I feared to destroy Power Meter's attenuator, instead!
Specs advertised are conservative, e. In reality you may achieve saturated Pout higher than advertised - 30Watt continuous if well cooled temperature not allowed to rise beyond spec. In AppNote, inside datasheet, short time-pulse output to 45Watt, DCsupply 9 to 16Volt, i.
Else, ships from LongIsland, NY, a company [not individual]. S website if they even posted it, as their core business is higher-end, so low-frequency amps don't always get posted directly at.
