0.5 TO 2 GHz DOUBLE-BALANCED MIXER
MODELS: DMO052LA2, DMO052HA2
FEATURES
• RF/LO coverage ......... 0.5 to 2 GHz
• IF operation ............... DC to 0.5 GHz
• LO power range
L ................ +7 to +13 dBm
H................ +17 to +23 dBm
• Conversion loss .......... 5.5 dB typical
• LO-to-RF isolation ....... 40 dB typical
MITEQ’s DM0052H and DM0052L mixers are constructed using a new microwave double-tuned RF/LO balun
(patent pending) that yields an IF response from DC to the lowest RF frequency. This design also produces
unusually high port-to-port isolation and further rejects out-of-band input signals with a “filter like” skirt selec-
tivity. This device performs as an up- or downconverter covering most PCN and communication applications
requiring high input signal levels (H version). The DM0052HA2 also makes an excellent high-level biphase test
modulator or detector with low DC offset voltage.
