Thick film chip attenuator replaces three or more discretes
Vishay Intertechnology has introduced a surface-mount thick film chip attenuator featuring a balanced Π filter schematic. Offered in a resistor array package, the CZB attenuator can replace three or more discrete devices, reducing board space requirements and simplifying the manufacturing process in telecomms and mobile wireless products.
As a single-component solution, the device delivers superior tolerance matching and temperature tracking for improved performance in signal attenuation applications. The CZB provides an attenuation range of 1.0 to 10.0dB with an attenuation tolerance down to ±0.3dB.
The attenuator features maximum power dissipation of 0.075W at +70°C, a frequency range to 3GHz, and impedance of 50 and 75Ω. The RoHS-compliant device operates over a temperature range of -55 to +150°C.
Samples and production quantities of the CZB are available now, with lead times nominally of 8-10 weeks.
