HMC519LC4TR
Brand: Analog Devices
The HMC519LC4TR is an Analog Devices (formerly Hittite) GaAs pHEMT MMIC low noise amplifier operating from 18 to 31 GHz, providing 14 dB small-signal gain with a 3.5 dB noise figure. With +23 dBm output IP3 and +11 dBm P1dB, it delivers high dynamic range for K-band and Ka-band receiver front-ends. The leadless 4 × 4 mm ceramic QFN surface-mount package ensures excellent RF performance at millimeter-wave frequencies. Operating from a single +3 V supply at 75 mA, it targets point-to-point radio, VSAT, and military SATCOM receivers.
