33 TO 37 GHz SINGLE-BALANCED MIXER
MODEL: SBW3337LG2
FEATURES
• WR28 waveguide RF input
• Coaxial LO/IF..................... DC to 4 GHz
• Usable with 1/3 LO frequency
• Field replaceable diodes
MIXER PRODUCTS
This mixer is designed for waveguide-mounted 35 GHz communication and radar applications. Low-level silicon
diodes require small LO power without bias. This mixer is also available with gallium arsenide diodes yielding high-
er IP
3
at proportionally more LO power.
