Peripheral Options

Duplexer

The Duplexer allows a single pair of transmit and receive channels to share a common antenna.

The duplexer requires 3 rack units of space and will always require a cabinet or rack to be

ordered (through the Parts department). The duplexer is factory tuned for single frequency

operation only. It is not available for cross-band operation.

UHF (403-524 MHz): The following peripherals are optional.

• 403-435 = 5MHz min/32MHz max (100dB isolation)

•

435-470 = 5MHz min/35MHz max (100dB isolation)

•

470-494 = 3MHz min/24MHz max (100dB isolation)

•

494-512 = 3MHz min/18MHz max (100dB isolation)

• ADD: DUPLEXER, UHF 403-435 MHz (X182UL)

• ADD: DUPLEXER, UHF 435-470 MHz (X182UM)

• ADD: DUPLEXER, UHF 470-494 MHz (X182UN)

• ADD: DUPLEXER, UHF 494-512 MHz (X182UH)

X182UL provides the option of using the same antenna for receive and transmit in the UHF (403-435

MHz) base station/repeater. If the X182UL is ordered, X265UL (ADD: NARROW PRESELECTOR,

380-435 MHz) is required. The TX and RX frequency separation must be at least 5 MHz.

X182UM provides the option of using the same antenna for receive and transmit in the UHF (435-470

MHz) base station/repeater. If the X182UM is ordered, X265UM (ADD: NARROW PRESELECTOR,

435-470 MHz) is required. The TX and RX frequency separation must be at least 5 MHz.

X182UN provides the option of using the same antenna for receive and transmit in the UHF (470-494

MHz) base station/repeater. If the X182UN is ordered, X265UH (ADD: NARROW PRESELECTOR,

470-524 MHz) is required. The TX and RX frequency separation must be at least 3 MHz.

X182UH provides the option of using the same antenna for receive and transmit in the UHF (494-512

MHz) base station/repeater. If the X182UL is ordered, X265UH (ADD: NARROW PRESELECTOR,

470-524 MHz) is required. The TX and RX frequency separation must be at least 3 MHz.

Narrow Preselector

The Base Station/Repeater Preselector rejects unwanted signals including the transmitter signals

from overloading the receiver. The filter is optional for the MTR3000 Base Station/Repeater.

This filter must be included to fulfill TIA102-CAAB Class A spurious response rejection (90

dB). The filter is usually not required when using a receiver multicoupler system since the

Preselector in the multicoupler should provide sufficient rejection.
