General Description
The HMC742HFLP5E is a digitally controlled variable
gain amplifier which operates from 0.5 GHz to 4
GHz, and can be programmed to provide from -19
dB attenuation, to 12.5 dB of gain, in 0.5 dB steps.
The HMC742HFLP5E 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 HMC742HFLP5E also features a
user selectable power up state and a serial output for
cascading other serially controlled Hittite components.
The HMC742HFLP5E is housed in an RoHS compliant
5x5 mm QFN leadless package, and requires minimal
external components.
