Application Information

The MAMX-011009 is designed to be economical

and easy to use. By employing a sub-harmonic

topology, the user only has to deal with one high

frequency port (RF). This simplifies system design,

lowers cost, and combined with an ultra-small

plastic package delivers a superior system solution.

The MAMX-011009 design allows bi-direction

frequency conversion (IF to RF or RF to IF). The

conversion loss, isolation, and linearity are similar

either way.

For proper up or down frequency mixing the

MAMX-011009 must be driven with sufficient power

to activate the mixing diodes, typically 14 dBm or

higher.

We

highly

recommend

M/A-COM

Technology Solutions MAAM-011101, which has

been engineered to match the LO requirements of

the MAMX-011009.

Grounding

The printed circuit board (PCB) layout is simple for

the MAMX-011009 since no external components

are needed. The LO port is internally DC blocked;

DC voltages up to 20 V are acceptable. However,

proper grounding must be used for operation. It is

recommended that the total common ground

inductance not exceed 0.03 nH. This is equivalent

to placing a least four 8-mil (200 μm) diameter vias

under the device, assuming an 8-mil (200 μm) thick

RF layer to ground. More ground vias are recom-

mended if possible.
