Modern software-defined tactical radios use sophisticated networking modulation formats and require advanced booster amplifier designs in their systems. AR Modular has two new products. The AR20R covers 225 MHz to 1.9 GHz with 20 W PEP output, and the AR55L provides 50 W PEP output across the 1.2 to 1.9 GHz band. Both offer switchable low-noise amplifiers with filtering to protect the receive path from co-site interference. Check out our full line of tactical amplifiers.

Reliability Advantages Of Modular Solid State Power Amplifiers Compared To Traveling Wave Tube Amplifiers
By Stephen Turner, VP of Engineering, Paradise Datacom
Amplifier manufacturers have long compared the advantages and disadvantages of solid state power amplifiers (SSPAs) and traveling wave tube amplifiers (TWTAs). Every few years, there is typically a technology advance that gives a slight advantage to one technology over the other. This paper shows how the modular design of SSPAs can provide dramatically higher levels of system reliability than TWTAs.

Continuous GSM Interference From Intermodulation
Because TX antennas have a higher field strength, they tend to interfere with RX channels. This application note discusses a case in which a continuous impairment in the GSM 900 band was affecting a cell phone station’s performance, and how Narda’s IDA 2 interference and direction analyzer was able to help.
