-161dBc PIM, 600-4000 MHz, IP67


221-600-4000 is a 4-Port, 3dB Hybrid Coupler that can used to combine any 2 signals in 600MHz – 4000MHz range, including the CBRS and C-Band. The combined signal will appear at both the output ports. These are symmetric devices so inputs and outputs can be used interchangeably. It can also be used to split one input signal into 2 output ports. The unused port must be always terminated with a 50Ω Load. These hybrid couplers can be used over a wide range of temperature and environmental conditions.
