A ruggedized four port selective multicoupler for 2.4 - 2.5 GHz:

• Gain: 16 dB, Noise Figure: < 2 dB, output isolation > 16 dB
• here is an overview photo of the amplifier/multicoupler (91k) module
• a view of the module DC input connector (67k) with protective cover
• and here is a view of the N type RF output connectors (79k) with protective covers
• the input SMA connector (69k) is protected by the carrying handle
• and a shot of the multicoupler with PSU cable, ready for field tests (80k)
• here is a simplified connection drawing (17k) of the multicoupler module
• this is the prototype measured overall frequency response (23k) (note notch filter)
• a closer view of the passband response (17k) at 5 dB/division
• and a even more zoomed view of the output level variation (16k) at 0.5 dB/division
