Integrate RF PA onto Tracksoar board. #29

Closed mkapuscik closed 5 years ago

mkapuscik commented 9 years ago

Implement discrete component or monolithic RF PA onto Tracksoar PCB for 144MHz.

mkapuscik commented 9 years ago

TI's CC11xx series monolithic transceivers have options that support 2-FSK modulation and the CC1120 "supports" down to 136.7MHz however is not characterized below 169 MHz.

what about the MAX2606, small package, low external part count, etc. coupled with a max2471 to up the output to around 25mw.

also an ADL5545 to up the transmit power to 250mw

Mike found a promising new chip, beat the info out of him so we can look into it.

here's an example max2606: http://ram.lijun.li/old/various/fm_xmtr.html

another possiblitity: http://digitalcommons.calpoly.edu/cgi/viewcontent.cgi?article=1156&context=eesp also max2470 is a whole thing, use the micrl300
