NXP® Semiconductors has announced its new higher power BTS7202 RX front end modules (FEM) and BTS6403/6305 pre-drivers for 5G massive multiple-input multiple-output (MIMO) going up to 20 W per channel. Developed and implemented in NXP’s silicon germanium (SiGe) process, the devices operate with modest current consumption to reduce operational costs for mobile network operators (MNOs). They also offer improved linearity and reduced noise figure to support better 5G signal quality.

As 5G networks continue to be built out across the globe, MNOs are increasingly leveraging 32T32R solutions to improve massive MIMO coverage in less dense urban and suburban areas. Utilizing 32T32R solutions requires using higher power devices that increase the power level per channel in order to achieve the total power required to ensure strong coverage of the 5G signal.

“With 5G networks beginning to densify, higher power solutions are crucial to ensure network and signal quality remain consistent,” said Doeco Terpstra, Vice President and General Manager, Smart Antenna Solutions, Radio Power, NXP. “Our customers recognize that higher power offers a way for network operators to address the power needs of 32-antenna systems without compromising network quality.”

The new BTS7202 RX FEMs and BTS6403/6305 pre-drivers offer a comprehensive and easily implemented solution for 5G base stations, complementing NXP’s power amplifier products for 32T32R radios. The BTS7202 RX FEMs feature a switch capable of handling up to 20-W of power leaking from transmit line-ups, reducing system complexity. The BTS6305 pre-drivers also integrate a balun to reduce costs.

In particular, the BTS7202U is a dual channel receiver FEM available in an HVQFN40 package. Designed for 5G mMIMO Infrastructure applications, it includes 2 independent receive channels each with a low noise amplifier (LNA). The gain can be set to two different gain levels. Each channel also has a switch to route high-power TX signals to a termination load.
