An improved GPS mast module is characterized by the following features: the GPS mast module may be connected in a HF main transmission line (7, 107) between a base station (BS) and an antenna assembly (ANT), in particularly a mobile radio installation, and the satellite signals from an internal or connectable GPS antenna (GPS-ANT) can be supplied by a directional coupler (23) to the HF main path (7, 107).

摘要:
An antenna transmission control device has a base-station-side and an antenna-side multiplexer circuit. There is an alternating protocol transfer between these two multiplexer circuits to control components close to the antenna. The current-alarmed or protocol-alarmed signals present at the antenna-side terminals of the multiplexer provided on the antenna side can be measured or detected by the multiplexer circuits and supplied to the transmission link together with a terminal-dependent or load-dependent protocol.

An improved device for receiving and transmitting mobile telephony signals comprises at least 4 channels. Each of the at least 4 channels (K1, K2, K3, K4) can be controlled with a transmission signal, that is different from the other channels, which can be generated with a separate channel module (KM1, KM2, KM3, KM4) from various data streams. A controller device is provided for, via which several or all of the power amplifiers, which are connected in several or all channels (K; K1, K2, K3, K4), can be operated in-phase or phase-locked with each other, in such a way that the transmission signals (TX) amplified in the channels concerned (K; K1, K2, K3, K4) can be synchronized and interconnected. As a result, a transmission signal can be radiated with a higher transmission power.
摘要:
An aerial transmission control device has a converter circuit. The converter circuit has at least one connection on the base station side, and at least one connection on the aerial side. The converter circuit is constructed so that when a load is connected, a power drawing which can be ascertained via the connection on the aerial side is measured in the converter, and so that at at least one connection on the base station side, the measured power drawing is fed in in the form of a protocol signal.
