General Description

GAIN: 15 dB typ.

1

GAIN ADJUSTMENT RANGE: > 20 dB

RELATIVE PHASE SHIFT: 10 DEGREES

The HMC152 is an amplifier with gain con-

trolled with a 5 bit binary word. The magni-

tude 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 modu-

lation 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.

Guaranteed Performance, -55 to +85 deg C
