The PE15A5101 from Pasternack Enterprises is a Temperature-Compensated Low Noise Amplifier that operates from 0.5 to 4 GHz. It provides a small signal gain of more than 35 dB with a noise figure of less than 4.5 dB and has a P1dB of 21 dBm. The LNA utilizes PIN diode compensation circuitry that adjusts gain levels as the device is exposed to temperature variations. It requires a DC supply from 12 to 15 V and consumes 350 mA of current.
The amplifier is available in a rugged aluminium module that measures 41.15 x 20.32 x 10.16 mm and has SMA-female connectors. It is suitable for use in aerospace and defense, test and measurement, microwave radio systems, military and commercial communication systems, research and development, RF front ends, SATCOM, wireless communications, and unmanned systems.
Temperature-Compensated Low Noise Amplifiers are amplifiers in which the DC supply is matched with the required value even if the operating temperature fluctuates. Varying temperature can lead to varying input supply readings which, in turn, can lead to variations in electrical parameters – such as gain, P1dB, efficiency – of the LNA. Temperature compensation precisely adjusts the input supply based on temperature sensor readings.
