no im not familiar with the hybrid pi model, I will google it. Thank you for the info, I mostly use fets and and small signal common transistors for switching. When I need gain I tend to lean twords an opamp, so I guess you could say im a bit lame with transistors when used out of the digital domain. I mean I know how to bias one and set up a simple one transistor or pnp/npn combo to do minor amplification to maybe buffer, drive LED, or hold a relay open but thats about it. When it comes to analog I acually understand mosfets much more and tend to use them over transistors whenever possible.
I am also fairly new to original RF designs beyond filters and antennas. Ive been learning about pin diodes and triplexers recently but I have never bulit a receiver or transmitter from scratch, mostly hacking on low noise filtered PSU's to lower noise floor and and preselectors is about what I know about RF electronics. I do a lot of SDR work as a hobby and am always looking for better front ends, I have just finished a project with a propeller chip connected to an antenna that uses a few counters to demodulate the AM band and output audio.
I usually buy my up/down converters and LNA's but I am getting more interested in what can do with hardware on the front end of an SDR. So my real question about this transistor specifically is, can it be used to amplify a input signal or is it to noisy and just meant for the TX side? I would be intrested in using it in a down converter im working on if it will work reasonably well as an RX amplifier. I dont have any plans to TX at 2-30 mhz so if it is more of a TX thing I will toss it back in the drawer along with the links you sent me and get to it at a later date. ALSO lastly is there a way to test this things with common tools? I dont have a meter with HFE since there only on crap DMMs, but I have a 2mhz signal gen and a scope. Maybe I could just use it to click a relay? If it does not work then its not even worth bothering with thinking of ideas for it! Any simple schematic would be appreciated that will allow me to test it without blowing it up, preferably one that doesnt need any pf caps or alot of specific nf caps.
