2 items left

Part Number: LNA600M4P2GR is flat-gain, high-linearity, ultra-low noise amplifier in a small 15/16”x1-1/8”x0.48” shielded RF enclosure. It has integrated LDO Linear Regulator with industrial leading low noise (11µv rms). The LNA provides a gain flatness of 2 dB (peak-to-peak) over a wide bandwidth from 1.5 to 3.6GHz.  At 2.6 GHz, the amplifier typically provides 20 dB gain, +39.5 dBm OIP3 at a 65 mA bias setting, and 0.6 dB noise figure. The LNA can be biased from a single positive supply ranging from +5 to +15 volts. It can be powered by wide categories of power supplies (e.g., USB, Car Battery etc.).
