Optimised for use in SATCOM, 5G wireless, test and measurement (T&M), EW and microwave radio applications, MACOM has announced the newest entries in its high-performance RF switch portfolio. The new GaAs-based SPDT MASW Series switches provide broadband frequency coverage and high-speed switching capability.

The new MASW-011105 SPDT reflective switch covers the 17.7-31GHz frequency range, with low insertion loss of 1.6dB, high isolation at 30dB and switching speed of 12ns, offered in a lead-free 3mm, 14-lead QFN surface mount plastic package. The new MASW-011107 SPDT non-reflective switch, offered in bare die format, covers the DC–26.5GHz frequency range, with low insertion loss of 1.3dB and high isolation at 46dB when operating at 20GHz. Both devices are fabricated via robust processes with full surface passivation aimed at providing high-performance and high reliability.

Graham Board, Senior Director of Product Marketing at MACOM stated: “MACOM’s heritage in high-performance RF switching is unassailable. We have lead the industry for decades by leveraging our proprietary AlGaAs, HMIC and GaAs technologies to deliver technically superior switch solutions. These new switches leverage our patented low gate-lag GaAs process. This technology will not only allow us to deliver best-in-class RF performance but also fast switching speeds, which is critical in TDD systems.”

MACOM’s heterogeneous semiconductor and packaging strategy is aimed to provide each individual RF system function is fully optimised to deliver maximum performance at the appropriate cost.
