Single National LM1820 chip provides all active stages for oscillator, mixer, IF amplifier, and AGC detector of superheterodyne AM broadcast radio. Omission of RF stage reduces cost at some sacrifice in sensitivity and stablity, along with more noise, but careful layout can minimize stability problems. Total gain is 88 dB. - Audio Handbook , National Semiconductor, Santa Clara, CA, 1977, p 3-4-3-8.
