Qorvo's C-band BAW BPF and switch/LNA saves space and weight of 5G radios
Date: 16/06/2023
Qorvo has made available of its new first bulk acoustic wave (BAW) 280 MHz band pass filter QPQ3509 for 5G C-band frequency applications in North America. Qorvo has also made available another new device QPB9850, a highly integrated front-end switch / low noise amplifier (LNA) module for 5G base station RF front-ends. The use of combination of these two new components in 5G small cell applications reduces size and weight.
Kyung Mun, principal analyst at Mobile Experts, Inc., said, “As the first frantic phase of 5G macro deployments tapers off in developed markets like North America, operators are turning their focus to the second phase of network densification with macro towers and small cells. Mobile Experts forecasts a 9% CAGR growth in 5G small cells over the next five years. In North America, we see an elevated growth of annual carrier outdoor small cell shipments over the next three years as operators look to harness their mid-band/C-band spectrum across their expanding 5G network footprint with small cells to further expand network capacity.”
The QPQ3509 filter covers the 3.7-3.98 GHz 5G band in a compact 2.0 x 1.6 mm package for base station applications. Low insertion loss coupled with high out of band attenuation makes this filter an excellent choice for 5G C-band applications. The QPQ3509 is part of Qorvo’s extensive portfolio of RF BAW and surface acoustic wave (SAW) filters.
The QPB9850 is a broadband, single-channel switch LNA module that integrates a 2-stage LNA providing functionality across 2.3-5 GHz to support various 5G bands including n41, n77, n78, and n79. The high-power handling switch can be used to protect the LNA when the radio is in transmit mode while also powering off the LNA. The QPB9850 provides 34 dB of gain at 3.6 GHz with 1.1 dB noise figure and high linearity with 31 dBm OIP3. The QPB9850 is available in a RoHS-compliant, highly compact 3 mm x 3 mm LGA package.
