Notes
[1] Any quality microwave diodes will work, like the 1N5711. Should be in a SMT package.
[2] Optional bandpass filter, not needed but highly recommended.
It's also possible to slightly increase the preformance of the pre-amplifier by using surface mount porcelain capacitors.
Also be sure to place the input and output matching capacitors in the exact locations as shown in the MAX2641 EVKIT datasheet.
