HMC939
1.0 dB LSB GaAs MMIC 5-BIT DIGITAL
ATTENUATOR, 0.1 - 40 GHz
v00.0910
Electrical Specifications, T
A = +25° C, With Vdd = +5V, Vss = -5V & VCTL = 0/ +5V
The HMC939 is ideal for:
Fiber Optics & Broadband Telecom
Microwave Radio & VSAT
Military Radios, Radar & ECM
Space Applications
1.0 dB LSB Steps to 31 dB
Single Positive Control Line Per Bit
±1.0 dB Typical Bit Error
High Input IP3: +43 dBm
Die Size: 2.36 x 1.02 x 0.1 mm
The HMC939 die is a broadband 5-bit GaAs IC
digital attenuator MMIC chip. Covering 0.1 to 40 GHz,
the insertion loss is less than 5 dB typical. The
attenuator bit values are 1.0 (LSB), 2, 4, 8, 16 for a
total attenuation of 31 dB. Attenuation accuracy is
excellent at less than ±1.0 dB typical step error with
an IIP3 of +43 dBm. Five control voltage inputs,
toggled between +5V and 0V, are used to select each
attenuation state.
