Description

M/A-COM’s MAMXSS0012 is a passive mixer that

achieves the performance of a double balanced

diode mixer in a lead-free SOT-25 package. The

MAMXSS0012 is ideally suited for use where high

level RF signals and very wide dynamic range are

required. Typical applications include frequency up/

down conversion, modulation, and demodulation in

receivers and transmitters for base station and

portable systems.

The MAMXSS0012 employs GaAs FETs as mixing

elements to achieve a very wide dynamic range in a

low cost plastic package. The mixer operates with

LO drive levels of +3 dBm to +8 dBm. The LO port

may be externally tuned for operation in various

frequency bands.

M/A-COM's GaAs IC is fabricated using a mature

0.5 micron gate length GaAs MESFET process. The

process features full passivation for increased

performance and reliability.

The spurious table shows the spurious signals resulting from the

mixing of the RF and LO input signals, assuming down

conversion. Mixing products are indicated relative to the IF. The

lower frequency mixing term is shown for two different RF input

levels. The top number is for an RF input power of 0 dBm, the

lower number is for -10 dBm.

Cross Section View

Recommended PCB Configuration

Layout View

The PCB dielectric between RF traces and RF ground

layers should be chosen to reduce RF discontinuities

between 50 Ω lines and package pins. M/A-COM

recommends an FR-4 dielectric thickness of 0.008‖ (0.2

mm) yielding a 50 Ω line width of 0.015‖ (0.38 mm). The

recommended metalization is 1 oz. copper.
