ORDERING EXAMPLE The ordering code of an ATV321 attenuator with 2±0.3 dB attenuation, supplied in 7-inch tape reel is: ATV321CR-072dBL. (6) RESISTOR TERMINATIONS L = Lead free terminations (pure Tin) NOTE 1. The “L” at the end of the code is only for ordering. On the reel label, the standard CTC will be mentioned an additional stamp “LFP”= lead free production. 2. Products with lead in terminations fulfil the same requirements as mentioned in this datasheet. 3. Products with lead in terminations will be phased out in the coming months (before July 1st, 2006) www.yageo.com Oct 12, 2004 V.0 Product specification Chip Resistors RF Attenuators AT SERIES 3 7 V321 (0404) / Pb Free MARKING No marking. CONSTRUCTION The attenuators are constructed on a high-grade ceramic body (aluminium oxide). The internal circuit is applied to the top surface of the substrate, and its design determines the required attenuation value. The attenuation layer is covered with a protective coating and a marking dot indicates input pin 1 as shown in the connection diagram of Fig.1. The rectangular marker designates input pin 1. 1 3 input signal Finally, the four external end terminations are added. To guarantee optimum solderability the outer layer of the terminations are lead free (pure Tin). attenuated output signal 2 4 HBK077 Fig. 1 Connection diagram DIMENSIONS Table 1 TYPE ATV321 L P L (mm) 1.0 ±0.10 W (mm) 1.0 ±0.10 T (mm) 0.35 ±0.05 A (mm) 0.33 ±0.10 B (mm) 0.15 ±0.10 P (mm) 0.65 ±0.10 D (mm) 0.25 ±0.10 T A B D W SCR019 Fig. 2 Attenuator dimensions For dimension see Table 1 www.yageo.com Oct 12, 2004 V.0 Product specification Chip Resistors RF Attenuators AT ELECTRICAL CHARACTERISTICS FOOTPRINT AND SOLDERING PROFILES Table 2 ATV321 / 40 mW CHARACTERISTICS Attenuation Range 1 dB to 20 dB 1 dB to 5 dB Attenuation tolerance 4 7 V321 (0404) / Pb Free SERIES ±0.3 dB (optional: ±0.2 dB) 6 dB and 10 dB ±0.5 dB (optional: ±0.3 dB) 15 dB ±1.0 dB (optional: ±0.5 dB) 20 dB ±2.0 dB (optional: ±1.0 dB) Characteristic impedance 50 Ω 1 dB to 10 dB DC to 2.5 GHz Frequency Range 15 dB and 20 dB DC to 2.0 GHz VSWR 1.3 max.
