The two EL2082’s are used as variable-gain IFamplifiers, with small gains offered by each. The output of the first EL2082 is coupled to the second bythe resonant matching network L1–C1. ForaQof5,Xc1... ...INshould be used. As before, current-feedback amplifiers tend to solve the problem. However, in thiscircuit the inherent phase lag of the EL2082 detracts from the phase margin of the op-amp, and someoverall bandwidth reduction may result. The EL2082 appears as a 3.0 ns delay, well past 100 MHz....
