The HMC1122 is a 6-bit digital attenuator operating from 0.1 GHz to 6 GHz with a 31.5 dB attenuation control range in 0.5 dB steps.
The HMC1122 is implemented in a silicon process, offering very fast settling time, low power consumption, and high ESD robustness. The device features safe state transitions and optimized for excellent step accuracy and high linearity over frequency and temperature range. The RF input and output are internally matched to 50 Ω and do not require any external matching components. The design is bidirectional; therefore, the RF input and output are interchangeable.
The HMC1122 operates on a single supply ranging from 3.3 V to 5 V with no performance change due to an on-chip regulator.
The device incorporates a driver that provides both serial and parallel control of the attenuator. The device also features a user-selectable power-up state and a serial output port for cascading other serial controlled components.
The HMC1122 comes in a RoHS compliant, compact, 4 mm × 4 mm LFCSP package, and is pin compatible to the HMC624A.
A fully populated evaluation board is available.
