主要規格如下:

at 10mhz, typical values are:

isolation: 100db

vswr: 1.05:1

insertion loss: 0.05db

because of the inherently good rf performance at lower frequencies, this product line is not tested below 2ghz except upon request.

voltage: 24 to 30vdc

coil resistance: 205 ± 15 ohms @ 20?c

current: 170ma max @ 28vdc and 20°c

switching time: 20 milliseconds @ 28vdc and 20°c

impedance: 50 ohms nominal

temperature: - 55°c to 85°c

vibration: 20g's sine/random

life: 1,000,000 cycles min

weight: 5.5 oz max for the sp6t
