VCXOs Offer Low Jitter
The V8F/V8M family of voltage-controlled crystal oscillators (VCXOs) are available at frequencies suitable for Gigabit Ethernet, backhaul communications, and test and measurement applications (including 122.88 MHz, 153.6 MHz, 155.52 MHz, 245.76 MHz, and ...
High-Power Coupler Collects 2 To 8 GHz
Model RCPL-2-8-30d-Nf-600W is a high-power coaxial directional coupler designed for use from 2 to 8 GHz. It can handle continuous power inputs to 600 W and peak input power levels to 10 kW. The component provides 3-dB coupling with Type N female ...
Know The Ins And Outs Of Testing IEEE 802.11ac
Currently, wireless-local-area-networking (WLAN) standards are evolving to satisfy an increasing number of usage models. These efforts have spawned two IEEE project groups. Working Group TGac wants to specify IEEE 802.11ac as an extension of 802.11n. ...
World IPv6 Launch Day Gets Backup
On June 6, numerous Internet service providers (ISPs), home-networking-equipment manufacturers, and Web companies all participated in World IPv6 Launch Day, transitioning their products and services over to the new IPv6 Internet protocol. Playing a ...
Kudos
Indium Corp.Has been recognized for its support of SMTA China. The company was named 2012 Member Sponsor of the Year at SMTA China's Annual Recognition Ceremony, which took place during NEPCON China in Shanghai. IEEE Communications Society (ComSoc)Is ...
The Final Round
After I presented my position based on facts and experiments ("Feedback," March 2012), Mr.Monzello attacks again, without any facts to support his erroneous position. GPS and satellite systems all utilize superheterodyne receivers with noise figures ...
OMTs Operate Over K- and Ka-Bands
Models SAT-KB-39642-T1 and SAT-KA-25028-T1 are full-band K-band (18.0 to 26.5 GHz) and Ka-band (26.5 to 40.0 GHz) orthomode transducers (OMT), respectively. These components separate orthogonally polarized signals within the same band, allowing two ...
Tiny Amp Offers Flat Gain To 6 GHz
Based on heterojunction-bipolar-transistor (HBT) technology, model CMA-62+ is an extremely broadband amplifier, with flat gain of 15 dB (typically 15.4 dB at 2 GHz) across a frequency range of 10 MHz to 6 GHz. The gain remains flat within 0.7 dB from 50 ...
Driver Amp Serves 30 To 4000 MHz
Suitable for military communications and commercial communications infrastructure applications, model MAAM-010617 is an RF driver amplifier with a frequency range of 30 to 4000 MHz. It offers 13-dB gain over that span, with 4.5-dB noise figure. The ...
Teseq Announces IFI Acquisition
In a move intended to broaden its product line in the RF-amplifier market, Teseq has unveiled plans to acquire Ronkonkoma, NY-based Instruments for Industry (IFI). Established in 1953, IFI designs and manufactures RF and microwave, solid-state, and ...
Test Titan Announces Acquisition
Adding to its already diversified portfolio of technology holdingsamong them, instrumentation, digital imaging products, and defense electronicsTeledyne Technologies has entered into a definitive agreement to acquire test and measurement house LeCroy ...
Latest Wi-Fi Certification Rolls Out
With more than 1 billion Wi-Fi devices shipped in 2011 alone, it's indisputable that wires are ceding ground to this technology in the so-called "digital home." Indeed, ABI Research predicts annual growth rate for Wi-Fi consumer devices over the next ...
Differential DCXO Boasts Sine-Wave Outputs
To alleviate issues like spurious noise and crystal resonator harmonics, a differential digitally controlled crystal oscillator (DCXO) with sine-wave outputs may present a suitable option for cellular applications. A signal-shaping technique was recently ...
Editor's Note
While all of us at Microwaves & RF appreciate the passion Mssrs. Polivka and Monzello have brought to this debate, we must eventually free our "Feedback" section for other contributors. Hence, we invited both authors to contribute their final comments ...
Cut PIM In Cables And Connectors
Passive intermodulation (PIM) is evidence of nonlinear behavior in a communications system and some of its components. PIM is caused by the mixing of multiple tones, which results in unwanted signals. If the levels of these signals are high enough, the ...
