Typical Applications
the HMC271ALP4(e) is a broadband 5-bit positive
control GaAs IC digital attenuator with CMos com-
patible serial-to-parallel drivers in a low cost lead-
less QFn 4x4 mm sMt package. Covering 0.7 to
3.7 GHz, the insertion loss is typically less than 2.5
dB. the attenuator bit values are 1 (LsB), 2, 4, 8,
and 16 dB for a total attenuation of 31 dB. Accuracy
is excellent at ± 0.4 dB typical with an IIP3 of up to
+48 dBm. Five bit CMos compatible serial control
words are used to select each attenuation state. A
single Vcc bias of +3V to +5V applied through an
external 5 kohm resistor is required.
the HMC271ALP4(e) is ideal for:
