2 TO 8 GHz TRIPLE-BALANCED MIXER
MODELS: TB0208LW2, TB0208LA1
FEATURES
• RF/LO coverage ......... 2 to 10 GHz
• IF operation ............... 0.5 to 10 GHz
• LO power range ......... +10 to +15 dBm
• Input 1 dB comp. ....... +5 dBm typical
• Packaging.................. Hermetically sealed
MITEQ’s triple-balanced TB0208L mixer series utilizes a dual-quad circuit to provide performance in overlap-
ping RF and IF frequency ranges. In addition to extremely broadband operation, custom-processed diodes
allow for minimal variation in conversion loss, extremely high third-order intercept and 1 dB compression
points versus input LO power range. Options for various drive level diodes provide numerous combinations of
intercept point and LO level.
