Functional Diagram

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.

Electrical Speciﬁcations, T_A= +25° C, 50 Ohm System Vdd = +5V, Vcc = +5V
