General Description
The HMC743LP6C(E) is a digitally controlled variable
gain amplifier which operates from DC to 4 GHz,
can be programmed to provide 63 dB of gain control
in 0.5 dB steps and delivers output IP3 of up to
+33 dBm. The gain control interface accepts a three
wire serial input word and allows independent or
simultaneous control of two 6-bit digital attenuators.
The HMC743LP6C(E) also features a user selectable
power up state and a serial output for cascading
other serially controlled Hittite products. The
HMC743LP6C(E) is housed in an RoHS compliant
6x6 mm QFN leadless package, and requires minimal
external components.
