HMC540SLP3E v00.0915 1 dB LSB SILICON MMIC 4-BIT DIGITAL POSITIVE CONTROL ATTENUATOR, 0.1 - 8 GHz Typical Applications Features The HMC540SLP3E is ideal for both RF 1 dB LSB Steps to 15 dB and IF applications: 0.2 dB Typical Step Error Low Insertion Loss: =< 1 dB Cellular Infrastructure High IP3: +56 dBm Wireless Infrastructure Single Control Line Per Bit Microwave Radio & VSAT TTL/CMOS Compatible Control Test Equipment and Sensors Single +3.3/+5V Supply 3x3 mm SMT Package ESD rating: Class 2 (2kV HBM) Functional Diagram Drop-in Replacement for HMC540LP3E General Description The HMC540SLP3E is a broadband 4-bit Silicon IC digital attenuator in a low cost leadless surface mount package. This single positive control line per bit digital attenuator utilizes off chip AC ground capacitors for near DC operation, making it suitable for a wide variety of RF and IF applications. Covering 0.1 to 8 GHz, the insertion loss is less than 1 dB typical. The attenuator bit values are 1 (LSB), 2, 4 and 8 dB for a total attenuation of 15 dB. Attenuation accuracy is excellent at 0.2 dB typical step error. The attenuator also features a IIP3 of +56dBm. Four TTL/CMOS control inputs are used to select each attenuation state. It can operate with a single Vdd ranging from +3.3V to 5V. Electrical Specifications, T = +25 C, With Vdd = +5V & Vctl = 0/+5V (Unless Otherwise Noted) A Parameter Frequency (GHz) Min. Typ. Max.
