HMC244G16

HMC244G16 Description

The HMC244G16 from Analog Devices Inc. is a high-performance SP4T (Single Pole 4 Throw) RF switch designed for applications requiring broadband operation (0Hz–4GHz) and low insertion loss. This surface-mount switch features an absorptive topology, ensuring minimal signal reflection and improved impedance matching (50Ω). With an insertion loss of just 0.7dB and isolation of 40dB, it delivers superior RF performance, making it ideal for radar systems, test equipment, and communication infrastructure. The switch operates on a 5V supply, supports high linearity (IIP3: 43dBm, P1dB: 25dBm), and is packaged in a strip format for easy integration.
