The 28GHz Pin Diode SP4T Switch serves as a critical component for systems requiring reliable switching capabilities at high frequencies. Operating between 24 to 32GHz, this switch provides low insertion loss of approximately 0.8dB while maintaining an isolation greater than 23dB. Such characteristics make it ideal for use in applications like phased array antennas and frequency routing within RF signal chains. The efficiency of design ensures minimal signal degradation across the frequency band, supporting high-performance outcomes in commercial and defense communication systems.
