General Description
The HMC742LP5E is a digitally controlled variable gain
amplifier which operates from 70 MHz to 4 GHz, and can
be programmed to provide from -19.5 dB attenuation,
to 12 dB of gain, in 0.5 dB steps. The HMC742LP5E
delivers noise figure of 4 dB in its maximum gain state,
with output IP3 of up to +39 dBm in any state. The dual
mode gain control interface accepts either a three-wire
serial input or a 6 bit parallel word. The HMC742LP5E
also features a user selectable power up state and a
serial output for cascading other serially controlled
Hittite components. The HMC742LP5E is housed in
an RoHS compliant 5x5 mm QFN leadless package,
and requires minimal external components.
