Where Are They Now? - Microwaves & RF
WEBDec 5, 2011 · LNR Communications is now part of L3-Narda in Hauppauge, NY. Logimetrics (a supplier of laboratory-grade traveling-wave-tube amplifiers) was absorbed into Instruments For Industry (IFI). IFI has confirmed that several of the Logimetrics guys are there and they can evaluate and/or repair Logimetrics amps.
Make Accurate Impedance Measurements Using a VNA
WEBJun 21, 2019 · The reflection accuracy (S11) of this device is specified to be ±0.4 dB for measurements from −15 to 0 dB. 2. The S5065 VNA has a measurement frequency range of 9 kHz to 6.5 GHz. Assuming that the datasheet spec of 0.4 dB for S11 accuracy is a 3σ spec, one sigma would be 0.13 dB, or 0.0154 in linear terms.
Comparing Narrowband and Wideband Channels - Microwaves & RF
WEBFeb 7, 2018 · In short, wideband channels can carry more information than narrowband channels, but they typically require more power to do so. Narrowband channels typically carry much less information than wideband channels and operate over shorter distances between transmitter and receiver. But because narrowband channels have less noise and typically lower ...
Learn About Circulators and Isolators | Microwaves & RF
WEBAug 20, 2016 · Circulators and isolators are three-port passive electronic devices that help direct the flow of microwave signals in RF equipment and systems. A port is defined as a connection point for either an input signal, output signal, or termination. Figure 1a shows the standard schematic symbol for a circulator. The arrow indicates the unidirectional ...
