This article lists RF Circulator manufacturers categorized by frequency range, suitable for various wireless technologies like WLAN, Zigbee, WiMAX, LTE, and VSAT, as well as cellular applications. These circulators come in different types, including drop-in, coaxial, and waveguide designs. Some are designed for narrowband use, while others are for broadband.

WLAN devices operate on RF frequency bands such as 2.4, 3.6, and 5 GHz. WiMAX supports bands from 3 to 3.6 GHz, 2.3 to 2.4 GHz, 2.5 to 2.7 GHz, and 5.8 GHz. Zigbee utilizes the 868/915 MHz and 2450 MHz bands. LTE, similar to GSM/CDMA/HSPA, uses bands like 800 MHz, 1800 MHz, and 2600 MHz. VSAT primarily uses the C and Ku frequency bands.

This guide covers vendors like M/A COM, ditom, Wenteq, Trak Microwave, novamicro, VIDA RF, and Channel Microwave.

Typical RF Circulator specifications include:

  1. Frequency range
  2. Isolation
  3. Insertion Loss
  4. VSWR
  5. Connector type
