F2480 Broadband RF Analog Variable Gain Amplifier

Renesas' F2480 is a wide bandwidth, high performance, analog controlled variable gain amplifier (AVGA). Flexible pinout enables either the amplifier or voltage variable attenuator (VVA) to be configured as the first stage in the cascade. The F2480 combines a VVA with Renesas’ exclusive Zero-Distortion™ RF amplifier in a compact package, delivering low insertion loss and high linearity for very precise and smooth adjustment of the RF attenuator.

The VVA has linear-in-dB attenuation tuning characteristics and superb IP3 performance over its full attenuation range. The amplifier has an OIP3 performance of +41.5 dBm at 900 MHz, while drawing only 106 mA. The device is internally matched so there is no need to optimize external matching elements.

Flexible enough to be used in either the transmit or receive path, the F2480 has 4 RF port pinouts supporting multiple lineup configurations with an amplifier range of 400 MHz to 3000 MHz, and an attenuator range of 50 MHz to 6000 MHz. Overall, it provides a 12 dB typical cascaded max gain with a 36 dB continuous gain range. The external pinouts allow products to be cascaded in any order desired.

The F2480 is ideal for such communications equipment as multi-mode, multi-carrier receivers, 3G/4G base stations, point-to-point and public safety infrastructure, and digital radio and communications systems.
