Overview
The HMC519LC4TR is a high dynamic range GaAs pHEMT MMIC low noise amplifier (LNA) produced by Analog Devices Inc. This amplifier operates within the frequency range of 18 GHz to 31 GHz, making it suitable for various high-frequency applications. It provides 14 dB of small signal gain, a noise figure of 3.5 dB, and an output third-order intercept (IP3) of +23 dBm. The amplifier requires a single +3V supply and draws a current of 75 mA. Its P1dB output power of +11 dBm enables it to function as a local oscillator (LO) driver for balanced, I/Q, or image reject mixers. The device features DC-blocked and internally matched I/Os to 50 ohms, enhancing its performance in microwave radio and VSAT applications.
