Ted Rappaport, founding director of NYU WIRELESS and a leading proponent of using the millimeter wave spectrum for wireless communications, discusses the FCC's recent rulemaking actions and technology developments that are paving the way to 5G.
Power, efficiency, and bandwidth. Werlatone provides all three qualities in its growing line of high power 2-way combiners/dividers. Model D9392 is no exception. Covering the full 500 to 2500 MHz, the D9392 is conservatively rated at 500 W CW, and operates with less than 0.3 dB of insertion loss.
Our newest addition to our 20 to 1000 MHz family of products is the Model D9317. This 200 W CW, 2-way combiner operates with less than 0.7 dB insertion loss, and a minimum of 15 dB isolation. Measuring just 3.75 x 3.75 x 0.9", the D9317 is ideal for combining four 50 W modules.
Werlatone introduces its new line of high power, absorptive filters with the Model AF9350. This UHF, low pass filter covers the 10 to 500 MHz band, and has an average power rating of 400 W CW. The AF9350 incurs a rejection of 45 dB minimum at the 750 to 3000 MHz band, and power rating of 25 W CW from 501 to 5000 MHz.
The Model AF9349 is a VHF, low pass absorptive filter, covering the 10-150 MHz bandwidth. This high power design is conservatively rated at 500 W CW (Pass Band), and 100 W CW (Stop Band). The Rejection is guaranteed at -50 dB from 300 to 1500 MHz.
Werlatone offers the Model C9688, a 40 dB dual directional coupler, covering the full 1 to 1000 MHz band. Rated at 800 W CW, the C9688 will operate into 3:1 Load VSWR, and is ideal for applications spanning multiple frequencies.
Werlatone supplies Model QH9304, a 90° hybrid coupler that covers the full 60 to 1000 MHz frequency band. This chemically bonded, multi-layered structure is provided as a drop-in unit, with tabs. Rated for 150 W CW, the QH9304 is ideal military and commercial applications.
The Model C9107 is a 53 dB dual directional coupler and is rated at 1000 W CW. This high power design covers the full 20 to 1000 MHz bandwidth, incurs only 0.4 dB of insertion loss, and offers a minimum 20 dB directivity. The C9107 is designed specifically for high power, multi-octave applications.
Werlatone’s breakthrough technology provides a new 2-way combining solution covering the full 3000 to 6000 MHz bandwidth. Model D9042 is rated for 250 W, at the sum port, and operates with an insertion loss of only 0.35 dB max. This small package size measures just 2.03 x 2 x 0.87” and weighs 5 ounces. Model D9042 offers excellent isolation of 15 dB min and is designed specifically for military and commercial applications.
2-Way 90° hybrid coupler - The QH9056 is a 4-port, hybrid coupler covering the full 30 to 520 MHz band. This stripline unit is designed for amplifiers and radios in the VHF/UHF band. Conservatively rated at 400 W CW, this unit eliminates ferrites and will withstand severe input unbalances. Low profile, fully bonded, and highly repeatable.
