AT-213-PIN Digital Attenuator Rev. V5 15.0 dB, 4-Bit, TTL Driver, DC-3.0 GHz Features Functional Schematic Attenuation: 1 dB steps to 15 dB Temperature Stability: 0.18 dB from 55C to RF2 RF1 +85C Typical 8 dB Low DC Power Consumption GND GND Hermetic Surface Mount Package GND GND 4 dB Integral TTL Driver GND GND 50 Ohms Nominal Impedance Vee GND Lead-Free CR-11 Package 2 dB 260C Reflow Compatible Vcc C1 RoHS* Compliant C4 GND Orientation Mark 1 dB PIN 16 C3 C2 PIN 1 Description M/A-COMs AT-213-PIN is a 4-bit, 1 dB step digital attenuator in a hermetically sealed ceramic 16-lead surface mount package. The AT-213-PIN is ideally suited for use where high accuracy, fast switching, very low power consumption and low intermodula- tion products are required. Typical applications in- clude dynamic range setting in a precision receiver circuits and other gain/leveling control circuits. Envi- ronmental screening is available.
