HMC305SLP4E v01.1015 GLITCH FREE 0.5 dB 5-BIT SERIAL CONTROL SILICON DIGITAL ATTENUATOR, 0.4 - 7.0 GHz Typical Applications Features The HMC305SLP4E is ideal for both RF and IF Glitch Free State Transitions applications: 0.5 dB LSB Steps to 15.5 dB Cellular Infrastructure TTL/CMOS Compatible Serial Data Interface Wireless Infrastructure SPI Compatible Serial Output Microwave Radio & VSAT Excellent Attenuation Accuracy: 0.25 dB Typical Bit Test Instrumentation Error Single + 3.3V to 5V Supply ESD rating: Class 2 (2kV HBM) Functional Diagram Drop-in Replacement for HMC305ALP4E General Description The HMC305SLP4E is a broadband 5-bit positive control Silicon IC digital attenuator with CMOS com- patible serial-to-parallel driver package in a lead- less QFN 4x4 mm SMT package. Covering 0.4 to 6 GHz, the insertion loss is typically less than 1.6 dB. The attenuator bit values are 0.5 (LSB), 1, 2, 4, and 8 dB for a total attenuation of 15.5 dB. Attenuation accuracy is excellent at 0.25 dB typical with an IIP3 of up to +52 dBm. Five bit serial control words are used to select each attenuation state. A single Vcc bias of +3.3V to +5V is required. Electrical Specifications, T = +25 C, Vcc = +3.3V to +5V A Parameter Frequency Min. Typical Max.
