Television If Amplifier with Phase-Correcting Interstage Network

A simple phase-correcting interstage network is used to improve the phase characteristic of a television-receiver i-f amplifier. In this way a more favourable amplitude characteristic and better selectivity could be obtained without impairing the transient fidelity. The gain is only moderately affected. These good effects are verified by measurements on a three-stage transistor i-f amplifier incorporating such a corrector.
