HMC305SLP4E v01.1015 GLITCH FREE 0.5 dB 5-BIT SERIAL CONTROL SILICON DIGITAL ATTENUATOR, 0.4 - 7.0 GHz ATTENUATORS - DIGITAL - SMT Typical Applications The HMC305SLP4E is ideal for both RF and IF applications: Cellular Infrastructure Wireless Infrastructure Microwave Radio & VSAT Test Instrumentation Functional Diagram Features Glitch Free State Transitions 0.5 dB LSB Steps to 15.5 dB TTL/CMOS Compatible Serial Data Interface SPI Compatible Serial Output Excellent Attenuation Accuracy: ± 0.25 dB Typical Bit Error Single + 3.3V to 5V Supply ESD rating: Class 2 (2kV HBM) Drop-in Replacement for HMC305ALP4E General Description The HMC305SLP4E is a broadband 5-bit positive control Silicon IC digital attenuator with CMOS compatible serial-to-parallel driver package in a leadless 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, TA = +25° C, Vcc = +3.3V to +5V Parameter Frequency Min. Typical Max.
