Functional Diagram General Description
The HMC742ALP5E is a digital y control ed variable S - D gain amplifier which operates from 70 MHz to 4 R GHz, and can be programmed to provide from -19.5 IE dB attenuation, to 12 dB of gain, in 0.5 dB steps. The HMC742ALP5E delivers noise figure of 4 dB LIF in its maximum gain state, with output IP3 of up to P +39 dBm in any state. The dual mode gain control M interface accepts either a three-wire serial input or a 6 bit paral el word. The HMC742ALP5E also features a IN A user selectable power up state and a serial output for A cascading other serial y controlled Hittite components. The HMC742ALP5E is housed in an RoHS compliant 5x5 mm QFN leadless package, and requires minimal LE G external components. B
