LTCC High Pass Filters for mmWave

Mini-Circuits has introduced new high pass filters that achieve breakthrough performance for Q-band and lower V-band applications up to 58 GHz. The HFCQ, HFCN, and HFCV LTCC filters offer a combination of low insertion loss, high return loss, excellent rejection, small size, cost-effectiveness, repeatability, ruggedness and reliability. These filters enable designers to cover filter blocks with traditional SMT technology versus more exotic solutions. Key benefits include smaller footprint compared to stripline filters, repeatable performance suited for volume production, and robustness. The filters simplify designs for applications like 5G FR2 and satellite communications. Mini-Circuits’ latest LTCC high pass filters set a new standard for electrical performance and ease of implementation in demanding mmWave systems.

MIMO Systems

In modern radio communications (particularly commercial cellular and Wi-Fi), Multiple-Input, Multiple-Output (MIMO) is a common method of utilizing multiple transmitting and receiving antennas to increase the capacity of the radio link, reduce errors, and maximize speed. As user demand for bandwidth and data speed have grown, MIMO systems have been integral in the evolution of modern communication systems including cellular communications, Wi-Fi networks and many more.

This article will explore the origins of MIMO technology and explain how concepts of polarization diversity and spatial diversity enable these systems to scale capacity for higher data rates and multiple simultaneous connections to user equipment. Use of MIMO in LTE-Advanced (LTE-A) communications and Wi-Fi 6/6E are then described by way of example.
