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