Attenuators
PRODUCTS AND SERVICES
Model 50HFFA-xxx-50/18 is a 50 Ohm coaxial fixed attenuator rated at 50 Watts average input power and operates DC-18 GHz.
These attenuator assemblies operate at 200-7125 MHz with an attenuation range of 0-95dB by 1dB steps.
The TSX Series of chip attenuators pushes the boundaries of SWaP in a cost effective, easy-to-implement surface mount solution, suitable for a wide array of applications.
The ADRF5474 is a 4-bit digital attenuator with 22 dB attenuation control range in 2 dB steps manufactured in a silicon process attached on a gallium arsenide (GaAs) carrier substrate. The substrate incorporates the bond pads for chip and wire assembly, and the bottom of the device is metalized and connected to ground.
The Skyworks family of wireless jitter attenuators offers CMOS integration, reduced power, low noise and size without compromising the stringent performance and reliability required in wireless applications.
The Model 50HFFB-xxx-5/40 DC-40 GHz attenuator is rated for a 5-watt average and is available with 2.92mm male/female connectors.
Model 50P-1501 is a 50 Ohm solid-state programmable attenuator with attenuation range 0 to 127dB by 1dB steps. It operates 200 MHz to 3 GHz and is rated for +20 dBm of RF input power. This step attenuator is available with BNC, N, or SMA coaxial RF connectors. The attenuator has seven individually controlled steps: 1dB, 2dB, 4dB, 8dB, 16dB, 32dB, and 64dB.
The Si5403B NetSync Network Synchronizer Clock utilizes DSPLL technology and is capable of meeting the requirements of SyncE-compliant wander filtering and software adjustment of output frequency and phase for IEEE 1588 applications.
ABOUT
Attenuators are the exact opposite of an amplifier. An attenuator is used to reduce the intensity of either electricity or sound. For example, the digital impulse that is used to drive a speaker may be stepped down to prevent the lower range speakers from failing. An equalizer in music is a form of amplifier and attenuator rolled up into one. However, it targets on particular frequency. Every instrument in a musical symphony and even the human voice occupy a certain frequency range. As an example, each note of a violin has a very specific frequency. The A string on a violin is exactly 440Hz. Using an attenuator, one can target the exact frequency of 440Hz and reduce its intensity. It can even be attenuated all the way down to zero. If this were to happen, then every time an A not of a violin was played, it would not be heard.
This sort of technology is used to clean up sounds of recordings and other sounds in a recording. It is even possible to pinpoint the frequency range of the human voice then use an attenuator to reduce it to zero. Imagine if one were to take a recording of a song and attenuate just the vocal portion, the song will now resemble a minus-one track.
Attenuators have other more sophisticated commercial uses. They can be used to reduce the electrical impulses that were amplified to travel long distances and may still carry strong energy when it arrives, so it needs to be attenuated before it is channeled for processing.
