Description

Channel Microwave AU323-5 Coaxial Isolator 800-900 MHz 23dB 1W SMA Female

A coaxial isolator that provides unidirectional signal transmission in the 800-900 MHz band. Prevents reflected power from damaging sensitive RF components by isolating forward and reverse signal paths.

Specifications & What's Included

  • Frequency Range: 800-900 MHz
  • Isolation: 23 dB Minimum
  • Insertion Loss: 0.4 dB Maximum
  • VSWR: 1.15:1 Maximum
  • RF Power: 1 Watt CW
  • Connectors: SMA Female (x2)
  • Operating Temperature: -25°C to +85°C
  • Unit only; no accessories included

Applications

Used in cellular base stations, RF amplifier circuits, and microwave test equipment from the 1990s-2010s. Commonly found in GSM, PCS, and early mobile infrastructure where protection of transmit amplifiers from load mismatch and reflected power was required. Operates in bands used by legacy cellular systems and industrial RF applications.

Condition: Used
This Channel Microwave AU323-5 coaxial isolator has been inspected and is in good used condition. The machined metal housing shows light surface scuffing and minor wear consistent with prior use, but is structurally intact with no damage to the body or connectors. Both SMA female ports are clean and undamaged. Please view our photo set and contact us if you have any questions. Please note: We have multiple units in stock — yours may not be the one shown in the photos, however, it will be similar in condition and function.
