Overview
The HMC342LC4 is a GaAs pHEMT MMIC Low Noise Amplifier designed and manufactured by Analog Devices Inc. (formerly Hittite Microwave Corporation). This amplifier is housed in a leadless 4x4 mm RoHS compliant SMT package, making it suitable for surface mount manufacturing techniques. It operates within the frequency range of 13 to 25 GHz, providing 22 dB of gain and +19 dBm of output IP3 from a single +3V supply. The low noise figure of 3.5 dB makes it ideal for receive and transmit pre-driver applications in various RF and microwave systems.
