AT-233-PIN Digital Attenuator Rev. V5 30.0 dB, 4-Bit, TTL Driver, DC-2.0 GHz Features Functional Schematic Attenuation: 2 dB Steps to 30 dB Temperature Stability: 0.18 dB from 55C to NC RF2 +85C Typical 16 dB Low DC Power Consumption +5V GND Hermetic Surface Mount Package -5V GND Integral TTL Driver 8 dB C4 GND 50 Ohm Nominal Impedance Lead-Free CR-12 Package C3 GND 4 dB 260C Reflow Compatible C2 GND RoHS* Compliant C1 GND 2 dB Description GND RF1 M/A-COMs AT-233-PIN is a GaAs FET 4-Bit digital PIN 16 PIN 1 attenuator with a 2 dB minimum step size and 30 dB total attenuation. This attenuator and integral TTL driver is in a hermetically sealed ceramic 16-lead surface mount package. The AT-233-PIN is ideally suited for use where accuracy, fast switching, very Pin Configuration low power consumption and low intermodulation products are required. Typical applications include Pin No. Function Pin No. Function dynamic range setting in precision receiver circuits 1 RF1 9 NC and other gain/leveling control circuits.
