AD6IW
High intercept low noise amplifier for L and S Band with Enhancement Mode Pseudomorphic
HEMT Low coast SMD SOT343 plastic package 4 lead SC70, positive gate voltage, up
to 6 GHz ATF55143
* 400 micron gate width,* 24 dBm output 3rd order intercept* 14dBm output power @ 1dB gain compression* low noise 0.6dB @ 2GHz* higher gain, but more unstable at low frequencies
ATF-551M4* SC70 MiniPak package* lower noise 0.5dB* higher P1dB 14.6dB* small package, difficult to solder
ATF54143* 800 micron gate width* very high OIP3 36dBm* 20.4 output power @ 1dB gain compression* low noise 0.5dB @ 2GHz* 16.6 gain @ 2GHz
