TDK Claims First Multilayer Bandpass Filter for Millimeter-Wave Bands in 5G Networks

TDK expanded its lineup of high-frequency multilayer products with the MMC series, presented as the first multilayer band-pass filter for the 28 GHz band in 5G mobile communication networks. The high-frequency component exhibits an insertion loss of 1dB, an attenuation of up to 30 dB, and a group delay of 0.25 ns. The device’s terminal design reliably suppresses frequency fluctuations in the millimeter wave bands. The 2.5 x 2.0 x 0.9 mm is well suited as a band-pass filter for high frequencies and spurious signals in the RF transceiver circuits of 5G base stations and other mobile communication equipment.
