A = +25 °C, 50Ω System, with Vdd1 = Vdd2 = +5V & Vctl = 0/+5V
the HMC759LP3e is a 7-bit BiCMos Digital
Attenuator in a low cost leadless sMt package. this
versatile digital attenuator incorporates off-chip AC
ground capacitors for near DC operation, making it
suitable for a wide variety of rF and IF applications.
the control interface is CMos/ttL compatible and
accepts a three wire serial input. the HMC759LP3e
features user selectable power up states and a serial
output port for cascading other Hittite serial controlled
components. the HMC759LP3e is housed in a
roHs compliant 3x3 mm QFn leadless package, and
occupies only 9 mm2.
