TL431 Crystal Radio Amplifier - Here is a simple audio amplifier using a TL431
shunt regulator. The amplifier will provide room-filling volume from an ordinary
crystal radio outfitted with a long-wire antenna and good ground. The circuitry is
similar in complexity to a simple one-transistor radio but the performance is far
superior. The TL431….(added 04/05/06) |

Trimless IF VCO: Part 1: Design Considerations - This App Note explores the design
fundamentals needed to implement a trimless, fixed-frequency, IF voltage-controlled
oscillator (VCO) and points out the challenges in guaranteeing proper circuit
operation. VCOs are essential components in the architecture of most wireless systems.
In dual-conversion approaches, a fixed-frequency.... APP 711: Feb 05, 2001

Tunable IF with TDA7000 - The main motive of the mods was not that the circuit
didn't work right, but were several tries to add some kind of frequency indicator to
the receiver. The left RCA plug and associated components are witnesses to the last
version, adding a FET buffer amplifiera and taking signal from the oscillator coil.
