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.
