What made you select Nuvotronics’ μMUX Multiplexers?
I chose the Nuvotronics μMUX multiplexer series because it solves one of the most persistent challenges in ultra broadband RF front-end design: achieving low insertion loss and high out-of-band rejection across multiple contiguous frequency bands without sacrificing size, weight, or manufacturability. In satellite communications, defense platforms, advanced test systems, and broadband telecom infrastructure, designers are routinely asked to cover wide spectral spans while maintaining strict isolation between channels and preserving system noise figure and linearity. Designing discrete filter banks to meet these requirements quickly drives up board space, alignment complexity, and cumulative loss. The μMUX family is perfect for these multi-channel receiver and transmitter architectures, where tight spectral partitioning, minimal SWaP, and repeatable production performance are mandatory.
From a technical standpoint, the μMUX series leverages Nuvotronics’ PolyStrata® micro-miniature coax technology to deliver near-ideal filter characteristics in a compact, surface mountable footprint. The result is low insertion loss and high rejection performance across DC to 40 GHz, depending on configuration, with excellent part-to-part consistency. The PSM0206B3S triplexer covers DC to 2 GHz, 2 to 3.5 GHz, and 3.5 to 6 GHz in a 25.7 x 26.5 mm SMT package weighing 3.7 g. The PSM0640B4S quadplexer spans DC to 6 GHz, 10 to 18 GHz, and 18 to 40 GHz in a remarkably compact 14.7 x 24.7 mm footprint at just 1.8 g. For broader channelization, the PSM0218B5S 5-channel multiplexer covers DC to 2 GHz, 2 to 4 GHz, 4 to 8 GHz, 8 to 12 GHz, and 12 to 18 GHz in a 26 x 26.5 mm package. All three devices support standard SMT assembly, which simplifies integration into high-density RF assemblies and supports scalable production.
