Made In USA

The fundamental application of the receiver multicoupler is to enable multiple radio receivers, spectrum analyzers or scanners, to share a common antenna system. The advantage of using a multicoupler in signal monitoring applications were several receivers are used (such as in SIGINT/COMINT), is in the port-to-port isolation of the coupler.

Isolation will reduce the possibility of RF interaction between receivers caused by local oscillators, synthesizers, etc. If an external pre-amplifier, receive filter or lightning protection device is used, only one is needed to service several receivers.


Both Passive and Active broad-band models as well as narrow-band specialty couplers are manufactured with premier components to meet a multitude of VLF to UHF monitoring applications. Standard port configurations from 2 up to 8 are available. These units are designed to meet most government, military and commercial radio monitoring demands. Active models include broad-band low-noise amplifiers, front-end protection, and, depending on model, input High-Pass or Low-Pass Filters.

Passive Multicouplers

HF to UHF  - 2 and 4 ports   (signal splitter/combiner)

The basic application of the passive multicoupler is to split a signal, in-phase, to the outputs. It can also act as a signal combiner with the ability to combine two or more signals, in-phase, to a common output generally called the “Sum” port. This feature is very useful in combining antenna signals for a receiving system, or, for laboratory use in combining RF signals for measurement and study. Because of the “passive” design they do not need power to operate.


 Our passive multicouplers are designed to operate to specifications in a 50 ohm system and all are compatible with any of the “active” multicouplers on this page. For example, a two port splitter such as the MC202 may be connected to two (2) MCA208M VHF/UHF couplers for a total of 16 ports, etc.


Please consult the table below for the model that best covers your intended frequency use range. Although they have substantial frequency overlap, the upper and lower frequency limits may be of importance.

Options:

(1):   PCB Conformal coating for high humidity installations.
(2):   TNC connectors.
