Profile: Electro-Metrics Corporation specializes in designing, producing & integrating antennas, sensors, & systems for broadband RF technologies. Antennas include bi conical, corner reflector, di pole, flat panel, horn, log periodic, monopole and parabolic antennas. The EM-4211 broadband amplifier is a very wide band, low noise and high gain amplifier. This device will improve the sensitivity of nearly all receiving devices. It is useful in improving the noise figure of typical low gain antenna and receiver combinations. This amplifier can be used with any 50 ohms passive transducer. Due to the small size and light weight of this device, it can be easily positioned very near the receiver device where it can provide signal acquisition capability. It requires 12V DC power source.
