Wireless Solutions BDA OVERVIEW: The Bi-Directional Amplifier (BDA) assembly provides an exceptional repeater/booster performances to extend the coverage area of radio communications in buildings and RF shielded environments. Features such as high linearity power amplifiers are contributing for the overall improved system linearity performances. The unit is based on a duplexed path configuration, having sharp out of band attenuation for improved isolation between the receiving and transmitting paths.

The isolation between the base station antenna and the mobile antenna should be at least 12 dB higher than the BDA gain.
Wireless Solutions AGC & MGC FUNCTION The BDA has AGC function. Their amplifier has a directional coupler and a detector at the output of the high power amplifier to monitor the output power. When a high signal is received the automatic level control detects the amplitude and sends a feedback signal to a voltage variable attenuator which attenuates the signal level so that the output power of the amplifier does not exceed the preset limit.
Wireless Solutions RF EXPOSURE WARNING In order to satisfy the FCC RF exposure requirements, you must ensure that the installation complies with the following: One antenna is connected via cable that has typical 1~10 dB attenuation (depends on the length of the cable) to the BDA BASE port. This antenna is installed outdoor and has very sharp beam (Yagi type or similar) pointed to the donor (BTS). This type of antenna has about 10 dBi gain. Typical specifications: gain: 8 dBd (=10.
