Renesas Electronics Corporation RF Amplifiers F1130NBGI

The F1130NBGI is a dual path lowband RF receiver designed for applications such as multi-mode, multi-carrier base station receivers. It operates within a frequency range of 400MHz to 1100MHz for RF, 500MHz to 1300MHz for LO, and 25MHz to 400MHz for IF. The device features a 19dB gain with a noise figure of 3.5dB and an output third-order intercept point (OIP3) of +37dBm when the RF amplifiers are not bypassed. The F1130NBGI includes a digital step attenuator with a 30dB adjustment range in 2dB steps, controlled via an SPI interface. Each RF amplifier can be bypassed for strong signal conditions, enhancing flexibility in various operational scenarios. The device is packaged in a compact 7 x 7 mm, 48-pin Thin QFN format, facilitating integration into receiver designs. It supports a total supply current of 360mA and operates within a temperature range of -40¬8C to +105¬8C. Engineers considering this product should note its low power consumption and low distortion characteristics, making it suitable for compact designs requiring efficient RF amplification.
