AT-106-PIN Digital Attenuator Rev. V10 50.0 dB, 6-Bit, TTL Driver, DC-2.0 GHz Features Functional Schematic Attenuation: 1 dB steps to 50 dB Temperature Stability: 0.18 dB from 55C to +85C Typical RF1 PIN 24 PIN 1 GND 32 dB Low DC Power Consumption GND GND Hermetic Surface Mount Package GND GND 16 dB Integral TTL Driver C32 GND 50 Ohm Nominal Impedance C16 GND 8 dB Lead-Free CR-13 Package Vee (-5V to -8V) GND 260C Reflow Compatible Vcc (+5V) GND 4 dB RoHS* Compliant GND C8 GND C4 2 dB Description C2 GND Orientation Mark GND C1 1 dB M/A-COMs AT-106-PIN is a GaAs FET 6-bit digital PIN 12 GND RF2 PIN 13 attenuator with a 1 dB minimum step size and 50 dB total attenuation. This attenuator and integral TTL driver is in a hermetically sealed ceramic 24-lead surface mount package. The AT-106-PIN is ideally suited for use where accuracy, fast switching, very low power consumption and low intermodulation products are required. Typical applications include Pin Configuration dynamic range setting in precision receiver circuits and other gain/leveling control circuits. Environ- Pin No. Function Pin No. Function mental screening is available.
