Nokia 468532A 2-Way GSM 1800/1900 MHz Multicoupler RMC M2HA w/ SMA Cables

Nokia 468532A 2-Way GSM 1800/1900 MHz Multicoupler RMC M2HA w/ SMA Cables

The Nokia 468532A is a 2-way RF multicoupler (Nokia designation RMC M2HA) designed for GSM 1800 and GSM 1900 MHz cellular network base station applications. It splits and distributes antenna receive signals across multiple receive paths within a Nokia BTS installation, allowing shared antenna use without significant signal degradation. The unit is housed in a compact, shielded aluminum enclosure with mounting brackets and uses gold-plated SMA connectors throughout.

Applications

RF multicouplers like the Nokia 468532A are used inside GSM base transceiver stations (BTS) to distribute a single antenna's receive signal to multiple receiver chains simultaneously. In a GSM 1800/1900 MHz network — commonly deployed for DCS 1800 (Europe/Asia) and PCS 1900 (North America) — the multicoupler sits between the antenna feed and the BTS receiver cards, enabling antenna sharing for diversity or multi-sector configurations without requiring separate physical antennas per receiver path. Nokia deployed components like the RMC M2HA series in their cellular infrastructure equipment from the mid-1990s through the 2000s as GSM networks were built out globally. Today, these modules are sought by organizations maintaining or repairing legacy Nokia GSM BTS installations, as well as by systems integrators working with surplus cellular infrastructure.
