actually i am using TGL2209-SM POWER LIMITER to handle high power at input stage, which is having 1 db insertion loss.

when i am feeding inputs in various combinations as shown below:

input powerlimiter (1db loss)o/p power level after limiterLNA(+16db gain)o/p power level of LNAFINAL POWER LEVELCONCLUSION
0dbm-1db-1dbm+16db+15dbm+15dbmok LNA will not goes into saturation bcoz P1db of LNA=19dbm.
1dbm-1db0dbm+16db+16dbm+16dbmok LNA will not goes into saturation bcoz P1db of LNA=19dbm.
2dbm-1db1dbm+16db+17dbm+17dbmok LNA will not goes into saturation bcoz P1db of LNA=19dbm.
3dbm-1db2dbm+16db+18dbm+18dbmok LNA will not goes into saturation bcoz P1db of LNA=19dbm.
4dbm-1db3dbm+16db+19dbm+19dbmok LNA will  goes into saturation bcoz P1db of LNA=19dbm.
5dbm-1db4dbm+16db+20dbm+20dbmok LNA will  goes into saturation bcoz P1db of LNA=19dbm.

my limiter (TGL2209-SM) limits power level up to 18dbm,but it is not required for present experiment.

T o overcome this issue i need go with another power limiter.

I want some other power limiter which limits <+5dbm.

I WANT KNOW how to handle power without power limiter?? but DON'T say using attenuation before or after power limiter.#
