Broadband, Flat Gain LNA
Tuning Range: 0.4 to 5.0 GHz
The GRF2105 is a broadband, ultra-low noise linear amplifier designed for small cell, wireless infrastructure and other high performance RF applications. The standard tune exhibits outstanding NF and linearity, return losses and enhanced gain flatness over 0.4 to 3.8 GHz.
Refer to the GRF2105 website landing page for a growing selection of application notes addressing specific application requirements such as improved return loss, operation to 5.0 GHz, etc.
Configured as a first stage LNA, linear driver or cascaded gain block, GRF2105 offers high levels of reuse both within a design and across platforms. The device is operated from a supply voltage (Vdd) range of 2.7 to 6.0 V with a typical bias condition of 5 volts and 70 mA for optimal efficiency and linearity.
The device is housed in a 1.5 x 1.5 x 0.5 mm 6-pin plastic DFN package.
