Electrical Specifications,
T
A = +25° C, With Vdd = +5V & Vctl = 0/+5V (Unless Otherwise Noted)
The HMC425 is ideal for:
Fiber Optics & Broadband Telecom
Microwave Radio & VSAT
Military Radios, Radar, & ECM
Space Applications
0.5 dB LSB Steps to 31.5 dB
Single Control Line Per Bit
±0.5 dB Typical Bit Error
Die Size: 1.5 x 0.85 x 0.1 mm
The HMC425 die is a broadband 6-bit GaAs IC
digital attenuator MMIC chip. Covering 2.4 to 8 GHz,
the insertion loss is less then 3.5 dB typical. The
attenuator bit values are 0.5 (LSB), 1, 2, 4, 8, and
16 dB for a total attenuation of 31.5 dB. Attenuation
accuracy is excellent at ±0.5 dB typical step error
with an IIP3 of +40 dBm. Six control voltage inputs,
toggled between 0 and +3 to +5V, are used to select
each attenuation state. A single Vdd bias of +3 to +5V
is required.
