fixed attenuator

Fixed attenuators in circuits are used to lower voltage, dissipate power, and to improve impedance matching.

The cabinet cover includes accessories such as an impedance adapter, fixed attenuator and antenna simulator.

Mode scramblers and fixed attenuators.

As an option, the attenuator pcb also includes provision for a 10dB fixed attenuator on the output side.

Generally these are switched, and should have a minimum step of 1 or 2 dB. You will need in addition fixed attenuators to add up to about 100 dB.

Mini-Circuits has introduced the NAT-3-60, a low cost semi-precision fixed attenuator operating in the wide DC to 6000 MHz frequency range.

A manual device is useful for one-time set up of a system, and is a near-equivalent to a fixed attenuator, and may be referred to as an "adjustable attenuator".

A selection of thirteen different attenuation values ranging from 1 to 20dB, excellent return loss, and flat attenuation over the broad DC-6000MHz band is what you get when you select from Mini-Circuits very low cost family of UNAT fixed attenuators.

Since this range is too sensitive for measurements near cellular base stations, the receiver is operated with a 20 decibel (dB) fixed attenuator between the antenna and the first amplifier which shifts the measurement range from 400 times below to 20 million times below the SC6 limit level.
