RF Isolator manufacturers based on frequency range, which can be used for various wireless technologies viz. WLAN, Zigbee, WiMAX, LTE, VSAT, cellular are listed below. There are different types based on layout drop-in, coaxial and waveguide type. Some are designed for narrowband applications and some are for broadband applications. To know more on isolator functions and applications refer our page on RF isolator in terminology section. WLAN supports devices at various RF frequency bands viz. 2.4, 3.6 and 5 GHz. WiMAX supports various RF bands 3 to 3.6 GHz, 2.3 to 2.4 GHz, 2.5 to 2.7 GHz and 5.8GHz. Zigbee supports two frequency bands 868/915 MHz and 2450 MHz.LTE supports various frequency bands of 800 MHz,1800 MHz,2600 MHz similar to used in cellular technologies GSM/CDMA/HSPA. VSAT supports C and Ku frequency bands.
