The LTC6433-15 from Analog Devices is a gain-block amplifier that operates from DC to 1.4 GHz. It delivers a gain of 15.9 dB with a P1dB of 19.2 dBm and has a noise figure of 3.22 dB at 150 MHz. The amplifier is internally matched to 50 ohms at the input and output, requiring a minimum of external components. It requires a 5V supply and draws only 95mA of current. The amplifier is available in a 4mm 4mm 24-lead QFN package with an exposed pad for thermal management and low inductance. On-chip bias and temperature compensation maintain performance over environmental changes.
