This single positive control line per bit digital attenuator utilizes an off chip AC ground capacitor for near DC operation, making it suitable for a wide variety of RF and IF applications. Typical insertion loss tracks within two percent for a given cable type, depending on the assembly length. This value was measured by using a detector in freespace, therefore additional losses can be expected if used as the intermediary element between two fiber-coupled components. 5 dB maximum. 25 V, the variable control voltage will range from 0 V to about 5 V. Vaunix solid state portable RF and microwave digital attenuators include 50 Ohm RF step attenuators with calibrated operation up to 20 GHz. 5 dB typical insertion loss and 30 dB nominal attenuation across the frequency range of 26. Attenuation can vary with certain intake conditions, and also in high volume and high temperature applications. Many fiber optical products may involve insertion loss and return loss, such as, patch cords , adaptors , attenuators , etc. Also it can be supplied with or without connectors. Insertion loss is 4. need for component and system loss simulation, instrument calibration, power meter linearity measurement and spectral tuning. The attenuator features low insertion loss, excellent attenuation accuracy, a 15 dB attenuation range, and high linearity. Quiet-Duct silencers (sound attenuators) are used to reduce airborne noise through commercial HVAC ductwork systems, building openings, sound enclosures, ventilating fans and plenum equipment. The total output insertion loss should be measured at each maximum insertion phase location on the phase tuner in order for the return loss to be calculated accurately. Characteristics Low Insertion Loss Wide Attenuation Range Low Back Reflection Dual Windows Low Wavelength and Polarization Dependent Loss (WDL / PDL) Used in In-line Power Control in Multi-channel Optically Amplified System, Transmitter Power Equalizationand and Laboratory R&D, It features high resolution and convenient manual adjustment. line, provides a total attenuation of 71 dB in 1-dB steps, offers respectable accuracy and insertion loss through 225 MHz and can be used at 450 MHz (see Table 1). Application note AP120 What is controlled impedance? discusses the importance of considering traces on high speed PCBs as transmission lines of known - and controlled - characteristic impedance. Phase Shift vs. , weighs only 12 oz. 5-dB (or 31. Attenuation (dB per 100 feet): MHz: 30: 50: 100: 146: 150: 440: 450: 1000: 2400 #2632: RG-174: 5. The higher the return loss, the. 2 dB less than shown in the plot; fixture losses were not fully deembedded. 54 dB insertion.
