Absorptive RF Switch with internal driver
The Big Deal
• High Isolation, 56 dB typ.
• High Input IP3, +46.5 dBm typ.
• Low insertion loss, 0.6 dB typ.
• Fast Rise/Fall time, 3.3 ns / 4.6 ns typ.
• Tiny Size, 3.25 x 3.25 x 0.9 mm
Mini-Circuits’ M3SWA-2-50DRB+ is a MMIC SPDT absorptive switch with an internal driver designed for
wideband operation from DC to 4.5 GHz supporting many applications requiring fast switching across a
wide frequency range. This model provides excellent isolation, fast switching speed and high
linearity in a tiny 3.25 x 3.25mm 8-Lead MCLP package.
Wideband, DC to 4.5 GHz
One model can be used in many applications, saving component count. Also ideal
for wideband applications such as military and instrumentation.
In the OFF condition, RF output ports which are not switched ON are terminated into
Ω. This enables proper impedance termination of the circuitry following the RF
output ports, preventing any unintended action such as oscillation.
• 62 dB at 1000 MHz
• 35 dB at 4500 MHz
High isolation significantly reduces leakage of power into OFF ports.
Input power at P1dB, 25.4 dBm typ.
Input IP3, +46.5 dBm typ.
High linearity minimizes unwanted intermodulation products which are difficult or
impossible to filter in multi-carrier environments such as CATV, or in the presence of
strong interfering signal from adjacent circuitry or received by antenna.
Form-fit compatible with M3SWA-250DR+
Fits into existing PCB footprint designed for M3SWA-2-50DR+ with minor electrical
Tiny size, 3.25 x 3.25 mm MCLP package
Tiny footprint saves space in dense layouts while providing low inductance, repeat-
able transitions, and excellent thermal contact to the PCB.
