Functional Diagram
Electrical Specifications, T
A = +25° C, 50 Ohm System Vdd = +5V, Vs= +5V
The HMC742HFLP5E is ideal for:
Cellular/3G Infrastructure
WiBro / WiMAX / 4G
Microwave Radio & VSAT
Test Equipment and Sensors
IF & RF Applications
-19 to 12.5 dB Gain Control in 0.5 dB Steps
Power-up State Selection
High Output IP3: +39 dBm
TTL/CMOS Compatible
Serial, Parallel, or latched Parallel Control
±0.25 dB Typical Gain Step Error
Single +5V Supply
32 Lead 5x5mm SMT Package: 25mm2
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.
