Duplexer MICRO4202
• Up to 150 W continuous input power
• Low Loss
• Compact dimensions
• Tuning to customer frequency
• 3 Year limited warranty

Compact duplexer is meant to provide frequency isolation between transmitting and receiving channels of duplex 400 MHz band radiotelephone systems. Combining small geometry with low loss and close frequency spacing advantages and with selective pass characteristics this duplexer is ideal for repeater and base station applications where higher input power and small physical dimensions together with cost considerations are critical.
Duplexer utilizes six high-Q notch-type coaxial resonators with 2”-cross-section that results in small geometry advantages without compromising duplex isolation. Due to right material choice and temperature compensated design temperature stability has been achieved.
The resonators are made of extruded aluminum passivated inside and outside with the galvanised steel chassis and teflon insulation has been applied in the coaxial cables and in the connectors.
Also available black paint coated.
The duplexer is capable of working continuously at up to 150 watt of power level.
The duplexer is tunable within the operating frequency range.
