45 GHz


Application-5g_MHF7The MHF 7 Micro RF Coaxial Connector sets a new bar for stamped component frequency performance. With a 1.68 VSWR max at 45 GHz, I-PEX provides unsurpassed performance in a small form factor 2.0 x 2.1 mm footprint and 1.40 mm mated height. Utilizing a proprietary method to control impedance, the MHF 7 Connector provides a low-cost alternative to millimeter wave applications up to 45 GHz. This connector is a prime candidate for use cases utilizing the 5G FR2 band’s mmWave frequencies (up to 45 GHz) not utilizing intermediate frequencies such as small cells, notebook PCs, fixed wireless access, and other CPE devices.


15 GHz



The NOVASTACK 35-HDN Connector is perfect for small spaces required by mobile phones and hotspots utilizing intermediate frequencies (IF) to 15 GHz before converting to mmWave frequencies. Its 0.35 mm pitch and 0.7 mm mated height make placement flexible for design engineers to maximize space. The patented 360-degree shield created by the mated pair greatly reduces EMI compared to a similar unshielded solution. The compact design and shielding is versatile for the challenges faced by smart phone and mobile hotspot engineers where space is critical.  Click to watch NOVASTACK 35-HDN product video.




The MHF 7S Micro RF Coaxial Connector represents a quantum-leap in stamped small form factor connector technology. Leading the way in EMI performance, the MHF 7S Connector redefines the boundaries of what is possible. The revolutionary design eliminates significant sources of EMI when transmitting IF frequencies to enable mmWave frequencies at the antenna module. As devices become more congested with RF signals this feature will aid in reducing noise and assist in passing regulatory emissions tests. In addition to reducing EMI, the MHF 7S Connector also has a 1.5 VSWR max through 15 GHz using a 2.0 mm x 2.0 mm footprint and 1.4 mm mated height. This connector’s superior EMI blocking design is ideal for mmWave devices utilizing intermediate frequencies up to 15 GHz. These devices include small cells, notebook PCs, fixed wireless access, and other CPE devices.
