Renesas Introduces 2-Stage 1.8 to 5 GHz RF Amplifier for 5G mMIMO Systems

Renesas Electronics Corporation, a premier supplier of advanced semiconductor solutions, has expanded its robust RF Amplifier portfolio with the new F1490 delivering much lower quiescent current (75 mA) than competitive solutions. The F1490 is a second-generation high-gain, 2-stage RF amplifier that covers the key sub-6 GHz 5G frequency bands from 1.8 GHz to 5.0 GHz. The amplifier benefits designers with simplified product selection for their transmitter (Tx) lineup, elimination of a gain block with better margin, two selectable gain modes for system design flexibility, lower power consumption, and superior performance.  

The F1490 delivers high gain with selectable modes and ultra-low power consumption while maintaining high OP1dB performance and 2.4 dB noise figure, to meet all the system-level requirements customers want from their massive MIMO 5G pre-driver.

Designed to operate from 1.8 GHz and 5.0 GHz, the F1490 RF amplifier features high gain, high linearity, and wide bandwidth, and is well suited for use with both FDD and TDD sub-6 GHz 5G applications. The F1490’s pin-to-pin compatibility with current devices lowers the cost of design updates.

Key Features of the F1490
  • Two selectable gain modes: 39.5 dB high gain or 35.5 dB low gain
  • High-performance OIP3 of 38 dBm and OP1dB of 24 dBm 
  • RF frequency range of 1.8 GHz to 5.0 GHz 
  • Ultra-low quiescent current of 75 mA
  • Supply voltage of 5V 
  • Up to +115°C TCB operating temperature

Today’s higher data rates drive the need for better radio signal-to-noise ratios, which translates to the need for Renesas’ higher linearity RF components. The company’s patented RF solutions with unique technical innovations address the evolving needs of a wide range of applications, including cellular 4G/5G base stations, communications systems, microwave (RF/IF), CATV, and test and measurement equipment. Renesas’ AAS solutions include interface amplifiers, low noise amplifiers, switches and pre-drivers to address the high performance transmit and receive requirements of massive MIMO with the highest efficiencies in the smallest form factors. 


Samples of the F1490 are available now in a 3 x 3 mm, 16-pin QFN package with mass production available in September 2020.
