The HMC1119 is a broadband, highly accurate, 7-bit digital attenuator, operating from 0.1 GHz to 6.0 GHz with 31.5 dB attenuation control range in 0.25 dB steps.

The HMC1119 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 is 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 HMC1119 has an on-chip regulator that can support a wide supply operating range from 3.3 V to 5.0 V with no performance change in electrical characteristics. The HMC1119 incorporates a driver that supports serial (3-wire) and parallel controls of the attenuator.

The HMC1119 comes in a RoHS-compliant, compact, 4 mm × 4 mm LFCSP package.

A fully populated evaluation board is available.

Product Details

The AD-FMComms11-EBZ board is a system platform board for communication infrastructure applications that demonstrates the Direct to RF (DRF) transmitter and observation receiver architecture. Using high sample rate RFDAC(s) and RFADC(s), a number of components in previous generation transmitters can be eliminated, such as mixers, modulators, IF amplifiers and filters. The objective being to bring the ADC or DAC as close to the antenna as possible, leading to possibly more cost effective and efficient communications solution.

It is composed of multi-GSPS RF ADC and DAC, AD9625 and AD9162 respectively. The transmit path contains a balun, low pass filter, gain block and variable attenuation to produce an output appropriate for a power amplifier module. Along the observation path, the PA output is coupled back into the board through a variable attenuator, a balun and finally the ADC. Clock management is taken care of on board; all the necessary clocks are generated from a reference. Power management is present as well.
