The Neat Adaptor, No Connector (NANo) waveguide-to-coaxial transition is designed to provide a direct, compact transition between a 50 ohm coaxial pin interface and waveguide; replacing the need for the bulky approach of semi rigid cable to conventional waveguide transition. The NANo solution offers improved mechanical integrity and optimizes the signal path while minimizing space envelope and reducing the number of possible failure points.
Building on the BSC Ultra Short End Launch Transition (USELT) range, the patented NANo design has comparable performance to precision right-angled transitions with more than 20 dB return loss (VSWR of 1.22:1) for most models. Band-optimized or wideband versions are available, the latter achieving typical bandwidths of above 60 percent of the standard waveguide operating band for the wideband versions.
Typical applications include direct integration of low noise amplifiers to waveguide-based systems. Testing of the LNA can be carried out using field-replaceable coaxial connectors, which are removed and replaced by the NANo. The NANo is then securely fixed to the LNA module, forming one mechanically integrated unit.
The NANo design interfaces directly to a hermetically sealed pin (glass to metal seal) hence fine leak sealing of the LNA or module can be achieved. The standard range of coaxial pin diameters can be accommodated (0.012, 0.015, 0.018 and 0.020 inch).
The NANo range is available in either brass or aluminium with silver plate or passivated finish. Devices can be provided painted, unpainted or primer-finished to allow painting once integrated into the final assembly.
