There are lots of nice low-noise FETs out there now, and most are very affordable. That's good news for us; my favorite device for 33 through 9cm is the Avago ATF-54143 E-PHEMET. The E-PHEMET is an enhancement-mode pseudomorphic HEMET...a mouthful for sure, but in simpler terms, it's the kind of GaasFet that is biased on with a positive voltage, eliminating the need to have a separate negative bias supply, or to float the source leads above DC ground, which often causes stability problems.
3456 (9cm) info
This close-up shows proper component placement for L band. Note the position of the shorting jumpers; about 2.5mm from the source leads.
For 13cm, changing L1 to 2.7nh and C1 to 3.9pf gets the job done nicely. Resistor R5 is not used on this band.
The placement of the shorting straps must also change to 1 mm from the source leads so that good input match can be maintained (see inset below).
These jumpers control the amount of degenerative feedback,
and their proper placement has a significant effect on gain and input match.
For 3456, here are the necessary component changes:
The other change to make is to cover the entire length of the
source traces with the shorting strap (see inset below).
This eliminates most degenerative feedback, and along with the
above component changes, optimizes the LNA for 9cm. As with the 13cm LNA, my
only measurements were of gain and input return loss, but these measurements
were very close to the ones in the Avago application note, which also lists the NF below
