Nortel NTQA50HB (telecommunications transmission and networking portfolio) Telecom System Card / Module

The Nortel NTQA50HB is a power amplifier module (revision HB) for the S8000/S12000 GSM base transceiver station cabinet, the stage that raises the transmit signal to the level the antenna feeder needs. It sits in the same PA family as the NTQA50EA and NTQA50SA modules used across this cabinet range, with revision and wattage varying by build. Because output power, GMSK linearity and connector layout are fixed at the board rather than configurable afterwards, the exact revision is worth confirming against the cabinet it is replacing. Nortel’s outdoor S-series GSM cabinets remain in service at a number of 2G sites still running on original hardware, and PA modules are one of the higher-wear components in that chain. Tell us the cabinet and sector configuration and we will confirm the unit we hold matches before it ships. Tech-Star (UK-based, shipped worldwide) sources and supplies Nortel hardware to order.
