4. Various chip attenuators
4.1 Attenuator for coaxial cable connector
Coaxial cables are used for high-frequency transmission. In many cases, an attenuator is mounted on the coaxial cable connector. In this case, a chip attenuator that matches the shape of the coaxial cable connector is required. The PAT series W type is ideal for this application.
The features of PAT series W type
・Double π circuit
・Ground and signal terminal locations match coaxial cable connectors
・Comes in 2 sizes. Both offer series of attenuation.
・Operating frequency of 10GHz is attained.
Mounting of PAT series W type
・In top view, 1 & 2 are the signal terminals and 3 is ground terminal.
・Terminal location shown matches coaxial cable connectors
・The outside of the coaxial cable connectors is soldered to the ground terminal of the attenuator.
4.2 Temperature compensated attenuator
In mobile phone base stations, there are cases where the temperature characteristics of high-performance amplifiers become an issue. Use a temperature compensated attenuator to alleviate this temperature characteristic and keep the output constant.
The features of P*V series
・Integration of an attenuator and a thermistor
・Attenuation changes automatically as temperature changes
・10 attenuation vales with various temperature coefficients
・Match amplifier temperature characteristics
・3 sizes, 10 attenuation and temperature coefficients
Application example of P*V series
As amplifiers gain decreases as temperature increases, the P*V’s attenuation decreases so that the gain stays constant.
4.3 High frequency chip attenuator
As typified by 5G mobile phones, higher frequencies are noticeable in the communications field. For 5G, use up to the 28 GHz band. The ATS series has been released as this high frequency chip attenuator.
The features of ATS series
・Attenuation to higher frequency range
・Matching circuits to 10 attenuation values
・Signal line is sandwiched by ground (SGS structure) – excellent heat dissipation and noise tolerance
・Small surface mount chip attenuator
ATS2012 Frequency performance of 10 attenuation values
Available from 0dB to 10dB with 1dB step
