The DM0052LA2 is a mixer that has been constructed using a new microwave double tuned RF/LO Balun that yields an IF response from DC to 500 MHz. It has a RF/LO Frequency from 0.5 to 2 GHz with an LO power range from 7 to 13 dBm. This mixer produces an unusually high port to port isolation and rejects out of band signals with a filter like selectivity. It can be used as an up-converter or down-converter in most PCN and communication applications.
