High-power PIN diodes for T/R switch applications

03-03-2016 | RFMW | Design & Manufacture

Now available from RFMW, two new Skyworks high-power PIN diodes target T/R
and attenuator applications. The SMP1331-085LF (shunt connected) and
SMP1331-087LF (series connected) diodes are capable of handling 50W CW power
in a shunt connected switch configuration. Large signal attenuator
applications ranging from 10 MHz to beyond 6 GHz are also possible.

Typical resistance for the SMP1331-085LF and SMP1331-087LF is 0.5ohm at
100mA and the maximum capacitance is 0.35pF at 30V. The low capacitance, low
parasitic inductance devices are ideal for use in land mobile radios and
infrastructure systems. Both Skyworks diodes are offered in a low profile,
ultra-miniature QFN 2mm x 2mm x 1mm package.
