Sinclair Q3220E uhf bpbr repeater duplexer/combiner
Here is some more information about the duplexer. The Q3220E duplexer utilizes Sinclair s Q-circuit design in a 4-cavity configuration to provide very high attenuation at extremely close frequency separation in the 430-475 MHz band. This design provides a quasi-bandpass response, resulting in suppression of spurious and sideband transmitter noise between, and adjacent to, the duplex frequencies. The typical isolation attained between duplex frequencies is greater than 45 dB.
Specifications for this model are as follows: FREQUENCY RANGE: 430-475 MHz, FREQUENCY SEPARATION: 5 MHz (min.), INSERTION LOSS: 2.5 dB (min.), ISOLATION: 70 dB (min.), MAXIMUM VSWR: 1.5:1, MAXIMUM INPUT POWER: 200 Watts, TERMINATION: N Female.
We will be adding new items regularly.
