SMIQ-5143H+ Description

Short technical summary and product information.

The SMIQ-5143H+ from Mini-Circuits is a passive, wideband in-phase/quadrature (I/Q) mixer. Fabricated using GaAs HBT technology, this mixer is suitable for both upconverter and image rejection mixer applications.

 

It covers a broad frequency band with RF and LO frequencies ranging from 5 to 14 GHz, and an IF frequency range from DC to 7 GHz. The SMIQ-5143H+ offers high image rejection, typically 30 dBc, and high isolation, with typical LO-RF isolation of 41 dB and LO-IF isolation of 46 dB. It also features a typical input IP3 of +27 dBm.

 

Designed for high-performance applications, this mixer provides superior dynamic range due to its passive nature, which results in a lower noise figure compared to active mixers. It requires no DC bias for operation.

 

The mixer is housed in a compact 4x4 mm 24-Lead QFN-style package, making it ideal for space-constrained designs. This industry-standard packaging facilitates ease of assembly in high-volume manufacturing processes.
