Featuring Shireen’s latest innovation and The world’s smallest bi-directional amplifiers (BDA), in its unique patent pending housing. A highly linear amplifier with Max saturated output designed in a completely weatherproof housing for all outdoor applications. Also available in PCB version for OEM customers and for the following frequencies: 300-500, 700, 900, 1300, 2400, 3500, 4400-5000 and 5700-5800 . Ideal for small housing where space limitations are critical.

Key Features:
Transmit Gain: Utilizing the latest Gallium Arsenide Heterojunction Bipolar Transistor (HBT), the unit provides highly linear gain.
LNA: The built-in Low Noise Amplifier RX signal gain improves the receive sensitivity of remote equipment,while keeping noise level very low.
Receive Filtering: All radio equipment contain filter for receive path. The band pass filter on this amplifier gives added protection against out of band noise.
Enclosure: The outdoor amplifier model is housed in patent pending Coax housing that does not require mounting hardware and seals to a completely watertight unit with a twist of hand. A state of the art unit.
Power consumption: With only 5 watt of power consumption during max transmit and low during Rx, Shireen’s BDA products offer great power consumption efficiency.
DC Injector:With only 1.2dB insertion loss, the BDA DC injector offer the lowest RF impact to ensure your RF system performance. Enclosed inspecially designed machined aluminum housing.
Radio Compatibility: Shireen’s BDA are designed for Time Division Duplex (TDD) radios.
Warranty: Shireen’s BDA products come with 2-year warranty.
