Functional Diagram General Description
the HmC680lp4(e) is a digital y control ed variable gain amplifier which operates from 30 to 400 mHz, 12 and can be programmed to provide -4 db to +19 db of gain, in 1 db steps. the HmC680lp4(e) delivers noise figure of 5 db in its maximum gain state, with t output ip3 of up to +40 dbm in any state. this high m linearity dVga also provides a differential rf output s which can be used to interface directly with saW filters in tx and rx applications, and with digital to l - analog converters in rx chains. the HmC680lp4(e) is housed in a roHs compliant 4x4 mm Qfn leadless ita package, and is CmOs/ ttl compatible. ig s - d r ie
