HMC230MS8 / 230MS8E v02.0505 4 dB LSB GaAs MMIC 3-BIT DIGITAL ATTENUATOR, 0.75 - 2.0 GHz 5 Typical Applications Features The HMC230MS8 / HMC230MS8E is ideal for: 4 dB LSB Steps to 28 dB Cellular Single Positive Control Per Bit PCS, ISM, MMDS 0.5 dB Typical Bit Error WLL Handset Pin - For - Pin Replacement to AA100-59 Digital Attenuator Base Station Infrastructure Functional Diagram General Description The HMC230MS8 & HMC230MS8E are broadband 3 - bit positive control GaAs IC digital attenuators in 8 lead MSOP surface mount plastic packages. Cover- ing 0.75 to 2 GHz, the insertion loss is typically less than 2 dB. The attenuator bit values are 4 (LSB), 8, and 16 dB for a total attenuation of 28 dB. Accuracy is excellent at 0.5 dB typical with an IIP3 of up to +48 dBm. Three bit control voltage inputs, toggled between 0 and +3 to +5 volts, are used to select each attenuation state at less than 50 uA each. A single Vdd bias of +3 to +5 volts applied through an external 5K Ohm resistor is required. Electrical Specifi cations, T = +25 C, Vdd = +3V to +5V & Vctl = 0/Vdd (Unless Otherwise Stated) A Parameter Frequency Min. Typical Max.
