Renesas recently unveiled two dual polarization beamforming ICs optimized for 2×2 antenna architectures for 5G mmWave and broadband wireless connections. They are said to offer best-in-class performance in the n257, n258 and 261. The more integrated F5288 and F5268 (8T8R) transceivers are packaged in 5.1 x 5.1 mm BGA packages and have the highest transmitter power output in the industry. They are designed for wireless infrastructure equipment, including base stations, mini and micro cell base stations, client-side equipment, fixed wireless access points (FWA), etc.
The manufacturer notes the use of unique DAP (Dynamic Array Power) technology in the F5288 and F5268, which provides high efficiency at various power output levels. The ICs are a third generation beamformer and offer all the beamforming capabilities required for 5G mmWave systems. In addition, the advanced RapidBeam digital control technology provides simultaneous synchronous and asynchronous control of multiple driver ICs, allowing “extremely fast” beam steering.
The F5288 is rated for 26.5-29.5 GHz and the F5268 for 24.25-27.5 GHz.
Combining the F5288 and F5268 with the F5728 up and down converters, the 8V97003 wideband millimeter wave synthesizer, power controllers, and other Renesas digital and analog products simplify system design.
F5288 and F5268 microcircuits and evaluation systems are already available for order.
