HMC349 RF Switch Module 3-5V 50 Ohm SMA Interface The HMC349 RF Switch Module is a high-performance, nonreflective, gallium arsenide single-pole, double-throw switch designed for operation from 100 MHz to 4 GHz. This module is ideal for applications in wireless infrastructure, mobile radios, and test equipment where high isolation and low insertion loss are critical. The module features a 50 Ohm impedance and is compatible with SMA connectors , making it easy to integrate into various RF systems. It operates on a single, positive supply voltage ranging from 3V to 5V and offers CMOS/TTL-compatible control logic. The HMC349 provides excellent power handling capabilities, with a typical 1 dB power compression of 34 dBm and a third-order intercept point of 53 dBm, ensuring reliable performance in demanding environments. Features: Made of material, corrosion‑resistant, anti‑oxidation, increased service life. High working frequency, increases the scope of application, strong practicality. The large heat dissipation area can increase the continuous working time. Advanced manufacturing technology, high reliability and stable performance. Built to meet standard specification, strictly follow factory quality control.
