HMC539ALP3E

HMC539ALP3/539ALP3E v01.0416 ATTENUATORS - DIGITAL - SMT 0.25 dB LSB GaAs MMIC 5-BIT DIGITAL POSITIVE CONTROL ATTENUATOR, DC - 4 GHz Typical Applications Features The HMC539ALP3/539ALP3E is ideal for both RF and IF applications: 0.25 dB LSB Steps to 7.75 dB • Cellular Infrastructure Low Insertion Loss: 0.7 dB • ISM, MMDS, WLAN, WiMAX, WiBro High IP3: +62 dBm • Microwave Radio & VSAT Single Control Line Per Bit • Test Equipment and Sensors TTL/CMOS Compatible Control ± 0.05 dB Typical Step Error Single +3V to +5V Supply Functional Diagram 3x3 mm SMT Package General Description The HMC539ALP3/539ALP3E is a broadband 5-bit GaAs IC digital attenuator in a low cost leadless surface mount package. This single positive control line per bit digital attenuator utilizes an off chip AC ground capacitor for near DC operation, making it suitable for a wide variety of RF and IF applications. Covering DC to 4 GHz, the insertion loss is less than 0.7 dB typical. The attenuator bit values are 0.25 (LSB), 0.5, 1, 2, and 4 dB for a total attenuation of 7.75 dB. Attenuation accuracy is excellent at ± 0.05 dB typical step error. The attenuator also features a high IIP3 of +62 dBm. Five TTL/ CMOS control inputs are used to select each attenuation state. A single Vdd bias of +3V to +5V is required. Electrical Specifications, TA = +25° C, With Vdd = +5V & Vctl = 0/+5V (Unless Otherwise Noted) Parameter Frequency (GHz) Typ. Max.
