Overview

0.5 dB LSB steps to 15.5 dB
Single positive control line per bit
±0.5 dB typical bit error
High input IP3: +45 dBm

Die size: 2.29 × 0.95 × 0.1 mm
4 × 4 mm, leadless, surface-mount technology (SMT) plastic package

The HMC941 devices are broadband, 5-bit, GaAs, IC digital attenuators available in a low cost, leadless, surface-mount package or in a monolithic microwave integrated circuit (MMIC) chip. Covering 0.1 GHz to 30 GHz or 33 GHz, the insertion loss is less than 4 dB typical. 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 ±0.3 dB or less than ±0.5 dB typical step error with an IIP3 of +45 dBm. Five control voltage inputs, toggled between +5 V and 0 V, are used to select each attenuation state.

Applications

Fiber optics and broadband telecom
Microwave radio and VSAT
Military radios, radar, and ECM
Space applications
Sensors
Test and measurement equipment
