General Description
The HMC152 is an amplifier with gain controlled with a 5 bit binary word. The magnitude of the voltage gain varies linearly with the value of the control word. This transfer function is used to perform weighted loading of antenna arrays, alignment of monopulse receivers, antenna nulling and digital modulation for communications. The amplifier provides low phase shift vs gain state. Intermodulation performance improves as gain decreases, which is opposite to what occurs in most voltage variable attenuators in which Intermodulation distortion degrades as attenuation is increased.
