Addressing 5G MIMO and backhaul radio systems, test and measurement equipment, radar, electronic-warfare (EW) and electronic-countermeasures (ECM) defense systems, as well as signal distribution networks, Mini-Circuits' MTX2-183+ wideband MMIC balun transformer exhibits an impedance ratio of 1:2, useful for applications from 2 to 18 GHz. The MMIC, leveraging gallium-arsenide (GaAs) process technology, offers excellent repeatability along with low insertion loss, low amplitude unbalance, and low phase unbalance, as well as a high level of common-mode rejection.
In addition, the 50-Ω, GaAs MMIC surface-mount balun has a secondary:primary impedance ratio of 2:1, well-suited for single-ended to differential conversion, with the typical full-band insertion loss ranging from 1.5 to 3.7 dB. Amplitude unbalance is typically 0.4 dB or better, and the phase unbalance is typically 2 deg. or better. The low insertion loss enables high-quality signal power transmission from input to output, and its common-mode rejection of 33 dB typ. enables rejection of undesired signals.
Provided in a 12-lead QFN-style plastic package measuring 0.157 × 0.118 in. (4 × 3 mm), the device saves space in dense layouts while providing low inductance, repeatable transitions, and excellent thermal contact to the PCB.
