2 TO 7 GHz DOUBLE-BALANCED MIXER
MODELS: DMX0207L, DMY0207L
FEATURES
• RF/LO coverage ......... 2 to 7 GHz
• IF operation ............... DC to 2 GHz
• LO power range ......... +7 to +13 dBm
• Conversion loss .......... 6 dB typical
• LO-to-RF isolation ....... 40 dB typical
MITEQ’s DMX/DMY series of mixers are constructed using double-tuned microstrip RF and LO baluns with a
DC-coupled IF structure. The construction, coupled with the hermetic packaging, provides for high inherent
reliability and isolation over an extremely broad frequency range. This device performs as an up- or downcon-
verter covering most EW bands and communication applications. This mixer is also available with medium or high for-
ward voltage diodes (M, H) yielding proportional changes in LO power and spurious performance.
