Microwave switch is also called radio frequency switch, this module covers DC - 8 G broadband frequency range, use - 5 v single power supply and control, covering L, S, C band, applied to 1.2 G, 1.5 G and 2.4 G, 3.5 G and 5.2 G, 5.8 G and other typical frequency points, has realized the control of microwave signal channel switching function, This module adopts SP4T single-pole four-throw mode to realize four-way signal selection, or one way signal selection through the control of which output, because of its low plug loss, wide band, high isolation, widely used in communication system equipment, using CNC structure shell, easy to install, stable and reliable performance Module parameters: 1, Model: SP4T ; 2, working frequency: DC-12G; working frequency: DC-8G working frequency: 0.1-6G working frequency: DC-3.5G 3, working mode: one choose four; 4. Typical insertion loss of DC-12G: 2.6dB@5.8G; Typical insertion of the DC-8G: 1.8dB@2.4G Typical insertion loss of 0.1-6G: 1dB Typical insertion loss of DC-3.5G :1.5dB(typical value) 5, DC-12G; Port isolation: 33dB@5.8G; DC-8G; Port isolation: ≥32dB@5.8G 0.1-6G; Port isolation: 45dB Typical value DC-3.5G; Port isolation: 30dB 6, impedance: 50Ω; 7, DC-12G power supply: ±3.3V dual power supply (low power, single-chip microcomputer can drive); DC-8G power supply: -5V power supply (low power, single-chip microcomputer can drive); 0.1-6G power supply: +3.3 to +5V DC-3.5G Power supply: +5V
