Radio Frequency Systems (RFS) introduces a dual-band bi-directional amplifier (BDA). The BDA amplifies the signal from a donor base antenna, which is then re-distributed via an indoor ‘service’ antenna system, providing coverage without the need for additional radios. The RFS 48960 BDA supports 800 MHz and 900 MHz specialized mobile radio (SMR) services in a single compact and lightweight unit. Providing a high gain of 65 dB to the signal at the base port, the 48960 BDA amplifies the weak signal to improve coverage in the service area. The BDA also has a high dynamic range of around 50 dB. In addition, the automatic gain control (AGC) feature prevents the amplifier from being overdriven, and also ensures that the unit will not exceed US Federal Communications Commission (FCC) limits of spurious emissions. Unlike other competition models, the AGC in the 48960 BDA utilizes a true root-mean-square (RMS) detector, which allows the AGC to be accurately set with a single tone, simulating a nearly true loaded signal as experienced in the field.
