HMC424LP3E General Description

The HMC424LP3E is a kind of broadband 6-bit digital attenuator in a low cost leadless surface mount package. The typical applications include basestation infrastructure, fiber optics & broadband telecom, microwave & VSAT radios, military & space and test instrumentation.

There are some features as follows: (1) 0.5 dB LSB steps to 31.5 dB; (2) single control line per bit; (3) +/- 0.5 dB typical bit error; (4) 9mm2 leadless SMT plastic package.

What comes next is about the absolute maximum ratings. (1): control voltage (V1 to V6) is from Vee to 0.5 V; (2): bias voltage range (Vee) is -7.0 V; (3): channel temperature is 150; (4): storage temperature is from -65 to +150; (5): operating temperature is from -55 to +85; (6): thermal resistance is 140/W; (7): RF input power (0.5-13.0 GHz) is +25 dBm.

HMC425 General Description

The HMC425 die is a broadband 6-bit GaAs IC digital attenuator MMIC chip. Covering 2.4 to 8.0 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.
