2-stage RF Amplifier offers High Gain

The Renesas, F1490 high-gain amplifier, two-stage RF amplifier offers two gain modes and spans 1.8 to 5.0 GHz.


RFMW announces design and sales support for a high-gain, two-stage RF amplifier. The Renesas F1490 offers two gain modes. In low gain mode, typical gain at 2600 MHz is 35.5 dB. In high gain mode, it’s 39.5 dB. Spanning a frequency range of 1.8 to 5.0 GHz the amplifier draws 75 mA from a 5 V supply for sub-6 GHz 5G applications. The devices’ high gain simplifies circuit design by eliminating a gain block function yet system flexibility is maintained via selectable gain control. Offered in a 3×3 mm QFN package.
