How do 5G eMBB and FWA data services compare?
Fixed-wireless access is a special use case of enhanced mobile broadband, one of the three use cases specified for 5G. FWA brings different challenges for deployment than eMBB.
Choose a 5G base station’s PA bias control circuit
Bias control of PAs is crucial to ensure optimum radio performance under all conditions. Current sensing and temperature sensing provides the feedback needed to control the PA bias. The choice of sensing and biasing circuits brings design trade-offs. 5G base station power amplifiers (PAs) need biasing using a separate bias controller to maintain optimum performance…
What is intermodulation, and is it good or bad? Part 2
A mixer can upconvert and downconvert a modulated signal with no loss of baseband information. Part 1 of this series described intermodulation resulting from the combining of two or more sinusoidal signals through a nonlinear device such as the mixer in Figure 1. The mixer’s output is the product of its two inputs, and its […]
Mixer converts 20 GHz to 80 GHz frequencies down to IF
mmTron Inc. announced an innovative active mixer providing frequency conversion from 20 to 80 GHz. In addition to its bandwidth, the TMC170D stands out with 0 dB average conversion loss across the band with an LO drive of only 0 dBm. The InP semiconductor-based design achieves RF and LO coverage from 20 to 80 GHz…
6G: Sub-THz device reaches 100 Gbps data rate
NTT DOCOMO, INC., NTT Corporation, NEC Corporation, and Fujitsu Limited jointly announced the development of a top-level wireless device capable of ultra-high-speed 100 Gbps transmissions in the 100 GHz and 300 GHz sub-terahertz bands. The four companies have been jointly conducting R&D on sub-terahertz devices since 2021 in anticipation of the coming 6G era. To…
mmWaves bring interconnect challenges to 5G and 6G
Signals in the mmWave range require extra care and more expensive components than at sub-6 GHz frequencies.
Solderless RF connectors attach to board edges for test applications
Samtec has released a new line of RF edge launch connectors with a narrow body design that is 33% smaller than traditional edge launch connectors.
