The MAMX-011009 comes in a 1.5 x 1.2 mm TDFN surface mount package, it has a single RF port, requires no biasing and has excellent 2xLO and 3xLO isolation eliminating the need for extra filtering. The device requires +15 dBm of LO power that can be easily attained by implementing the MAAM-011101, which is a single bias low cost 4-20 GHz buffer amplifier offered by MACOM.
The part can be used for up or down frequency conversion. The mixer integrates an 180° balanced diode topology that allows the LO to be injected at ½ the LO mixing frequency, which improves isolation and simplifies system requirements for the customer. Samples are available from stock.
