COMPONENTS / SUBSYSTEMS NEW PRODUCTS & SERVICES Orthogonal Mode Transducer Offering for Microwave Antennas Radio Frequency Systems (RFS) has announced the availability of an orthogonal mode transducer (OMT) compatible with multiple antennas in the company's portfolio of microwave products. Designed for maximum flexibility and futureproofing, RFS OMT enables users to implement a "pay as you grow" scheme for up to four outdoor units (ODUs). OMT reduces costs and improves the system's competitiveness and reliability by eliminating twistflexes between the ODUs and the antenna. RFS OMT can be purchased in conjunction with specified RFS antennas or separately for RFS antennas already installed in the field. OMTs are multi-port microwave couplers that combine two cross polarized RF signals, allowing multiple ODUs, operating on different polarizations to operate simultaneously on one antenna. RFS OMT addresses the industry's increasing need for dual-polarized direct mount antennas for higher capacity bandwidth, which are well-suited for 4G and LTE applications. RFS OMT portfolio is comprehensive; available in frequencies from 6 GHz to 25 GHz with customized interfaces for several microwave radio manufacturers. It is compatible with RFS' 1 foot to 6 feet, SB1, SC2, SC3, SB4, SB6 series antennas. RFS OMT starts with a two-port OMT (2+0) and allows for the addition of two couplers as needed (2+2 or 4+0), with no mechanical interference with the antennas due to the slanted/vertical shape of the OMT. OMT has been fully tested in real wind tunnel conditions with wind speeds up to 250 km/h to ensure durability and survivability. Electrical and mechanical qualifications have been successfully completed, such as return loss, insertion losses, vibrations and waterproofness. High Gain Amplifiers for Commercial and Military Radar Pasternack Enterprises, Inc. has released a new portfolio of L and S band high gain amplifiers covering 1.2 to 1.4 GHz and 3.1 to 3.5 GHz specifically used for commercial and military radar applications as well as observation satellites and communications systems. Pasternack's new high gain amplifier modules are optimized for 1.2 to 1.4 GHz and 3.1 to 3.5 GHz radar applications, packaged in hermetically-sealed metal enclosures and exhibit improved performance in high gain, gain flatness, high output power and low noise. These RF amplifiers utilize a hybrid microwave integrated circuit design and advanced GaAs pHEMT technology to produce an unconditionally stable module. They are also designed with built-in voltage regulation, bias sequencing, and reverse bias protection for added reliability and over-voltage protection is installed externally for easy repair. A total of six new L and S band high gain amplifiers are offered in this latest release from Pasternack. Two of those products are low noise amplifiers (LNA) which demonstrate noise figure performance of 1.1 dB to 1.5 dB at high gain levels of 40 dB typical gain while also exhibiting improved gain flatness. Also offered are 10 watt and 20 watt high power amplifiers that have exceptional gain performance of 40 to 47 dB with 1.0 dB to 1.5 dB gain flatness. Pasternack is also releasing an L-band driver amplifier that displays solid gain performance of 47 dB while delivering competitive gain flatness of 1.5 dB. The 1.2 to 1.4 GHz and 3.1 to 3.5 GHz high gain amplifiers from Pasternack are in stock and available to ship the same-day.
